A research team led by Duan Luming at the Institute for Interdisciplinary Information Sciences at Tsinghua University in China has built the worlds most powerful ion-based quantum computing system, the South China Morning Post reported. The research achievement paves the way for scalable quantum computers in the future.

Considered the next frontier of computing, quantum computers promise faster computation that could help humanity solve challenges in medicine, astronomy, and climate change. This is achieved by using quantum bits or qubits to store information.

Unlike the classical bits in silicon-based computers, which can either be in an on state or off state, qubits can be both on and off simultaneously while occupying a range of states in between them, also known as superposition. This allows quantum algorithms to process information in a fraction of the time it takes for even the worlds fastest supercomputers.

Researchers are working with various quantum systems to determine the best way to work with qubits.

Ions or charged particles can be suspended using electromagnetic fields and used as qubits in a quantum system. However, previous work in this area has shown that although quantum information can be transferred using the collective motion of the ions, the system isnt suited for scaling up.

Just as scaling silicon-based computers helps achieve complex calculations, scalability is important in quantum computing as well. To overcome this challenge with ions, researchers have used trapped-ion systems instead.

In such a system, researchers use a one-dimensional ion crystal that binds the ions in a lattice structure within, hence the name trapped-ion system. The approach is quite popular among quantum physicists, who have achieved simulation with 61 ions so far.

The researchers in Duans team at Tsinghua University have created a record by achieving stable trapping and cooling of a two-dimensional crystal with 512 ions, a first in the field of quantum science.

The achievement was praised by reviewers as a milestone to be recognised at the journal where Duan and colleagues published their research findings, the SCMP report added.

The feat achieved by the Chinese researchers is important given that scalability with ions has been a problem in quantum computing before. The researchers demonstrated this ability in a stable quantum simulation system, which another reviewer of the paper dubbed the worlds largest simulation.

Quantum simulators are devices that help researchers find answers about quantum model systems by analyzing quantum effects. They are popular tools among researchers because they can help advance scientific knowledge about quantum systems.

The researchers also completed another simulation, using 300-ion qubits to successfully complete a quantum calculation. The SCMP report said that such a systems computational ability was already astronomical and far exceeded the capabilities of classical computers.

The research moves China closer to building large-scale quantum computers in the future, an area in which it is directly competing with the US. Interestingly, Duan, a doctoral student from the University of Science and Technology of China, spent 15 years teaching in the US before returning to China in 2018.

The research findings were published in the journal Nature this week.

China builds the world's most powerful ion-based computing machine - Interesting Engineering

Chinese scientists are one step closer to a future large-scale quantum computer after building the worlds largest quantum simulation machine based on the trapped-ion technique, praised by one academic journal reviewer as a milestone to be recognised.

The breakthrough was achieved under the leadership of Duan Luming, a quantum physicist renowned for his pioneering research, who returned to China in 2018 after 15 years of teaching in the United States.

Duan received his doctorate in 1998 from the University of Science and Technology of China, the countrys premier institute for quantum research, before joining the University of Michigan in the early 2000s.

Since his return, he has been a full-time professor at Tsinghua Universitys Institute for Interdisciplinary Information Sciences.

Duan and his colleagues, along with several research groups at universities and hi-tech companies around the world, have been chasing the trapped-ion approach to qubits.

Quantum bits, or qubits, are the building blocks of quantum computers, just as bits are in regular computers.

However, qubits are extremely difficult to harness in a controlled and repeatable way because of what is called their hazy nature.

Regular bits can be described as switches that are either on or off. But because uncertainty and probability hold sway in quantum physics, qubits can be both on and off at the same time, and also exist in a variety of in-between states.

Ions, or charged atomic particles, can be trapped and suspended in free space using electromagnetic fields. The qubits are stored in stable electronic states of each ion, and quantum information can be transferred through the collective motion of the ions in a shared trap.

But scalability remains a key challenge for this system.

This is where the trapped-ion approach comes in, as it offers one of the most promising architectures for a scalable, universal quantum computer.

Researchers earlier achieved quantum simulations with up to 61 ions in a one-dimensional crystal. Ion crystals are solids made up of ions bound together in a regular lattice the symmetrical three-dimensional structural arrangements of atoms, ions or molecules inside a solid.

But Duan and his teams quantum simulator was able to achieve the stable trapping and cooling of a two-dimensional crystal of up to 512 ions, in a first for science.

The feat holds great significance for the future of quantum computing, given that scalability is a major hurdle. The teams scaling up of the ions in a stable simulation system is seen as likely to pave the way to building more powerful quantum computers.

The findings of their study were published on Wednesday in the peer-reviewed journal Nature.

This is the largest quantum simulation or computation performed to date in a trapped-ion system, commented one reviewer.

Quantum simulators are devices that actively use quantum effects to answer questions about model systems and, through them, real systems. They are increasingly popular tools in the world of quantum computing for their role in advancing scientific knowledge and developing technologies.

Duan and his team also managed to perform a quantum simulation calculation using 300-ion qubits. They found the computational complexity of 300-ion quantum bits working simultaneously to be astronomical, far exceeding the direct simulation capability of classical computers.

As technology continues to advance toward higher realms, a new mechanism has entered the crosshairs of scientists: quantum computing. This process uses the principles of fundamental physics to "solve extremely complex problems very quickly," according to McKinsey & Company.

Using logic-based computing to solve problems isn't a new phenomenon; it was (and remains) the basis for artificial intelligence and digital computers. However, quantum computers are "poised to take computing to a whole new level," McKinsey said, because the introduction of physics into computing has the "potential tosolvevery complex statistical problems that are beyond the limits of today's computers." Quantum computing alone "could account fornearly $1.3 trillion in valueby 2035."

However, while organizations like McKinsey are clearly high on the potential for quantum computing, others say that it could create a slew of new problems.

Quantum computing is a huge leap forward because "complex problems that currently take the most powerful supercomputer several years could potentially be solved in seconds," said Charlie Campbell for Time. This could open "hitherto unfathomable frontiers in mathematics and science, helping to solve existential challenges like climate change and food security."

Quantum computing is already being used for more practical purposes. One company called D-Wave Systems has "used its quantum computer to help clients determine driver schedules for grocery-store deliveries, the routing of cross-country promotional tours and cargo-handling procedures at the port of Los Angeles," said Bob Henderson for The Wall Street Journal. It could even help optimize seemingly minute problems, such as the arranging of planes at airport gates. If trying to arrange just 50 planes at 100 gates, the number of possibilities would be "10 to the hundredth power far more than the number of atoms in the visible universe," said Henderson. No standard computer "could keep track of all these possibilities.But a quantum computer potentially could."

While ubiquitous usage of quantum computers is a long way away, there are some strides being made, as Google "has built a quantum computer that's about 158 million times faster than the world's fastest supercomputer," said Luke Lango, a senior investment analyst at InvestorPlace. And quantum theory in general "has led to huge advancements over the past century. That's especially true over the past decade," as scientists "have started to figure out how to harness the power of quantum mechanics to make a new generation of superquantum computers."

But with new advancements come new sets of problems. Case-in-point: Quantum computers have "become a national security migraine," said Campbell for Time, because its ability to solve problems "will soon render all existing cryptography obsolete, jeopardizing communications, financial transactions and even military defenses."

This would be "potentially a completely different kind of problem than one we've ever faced," Glenn S. Gerstell, a former general counsel for the National Security Agency, said to The New York Times. There may be "only a 1% chance of that happening, but a 1% chance of something catastrophic is something you need to worry about." This risk "extends not just to future breaches but to past ones: Troves of encrypted data harvested now and in coming years could ... be unlocked," said Zach Montague for the Times.

Even as the risks are documented, investors are working to ensure quantum computers can be used on a widespread scale. Curtis Priem, the co-founder of AI chip manufacturer Nvidia, is "looking to establish New York's Hudson Valley as an epicenter of quantum-computing research in the country," the Journal said. Priem has already donated more than $75 million to develop a quantum computing system at Rensselaer Polytechnic Institute, making it the first college campus in the world with such a device.

Others are looking at the future of the industry through a more financial lens; Illinois legislators will soon be "asked to consider a series of incentives" as part of the state's "intensifying push to become the nation's hub for quantum computing," said Crain's Chicago Business. One of these major proposals is the creation of an "'enterprise zone' that would allow the state to provide quantum companies exemptions from sales, payroll and utility taxes for up to 40 years." If lawmakers in Illinois pass these incentives, there is a high chance that other states could follow.

Researchers from Cleveland Clinic and IBM have recently published findings in the Journal of Chemical Theory and Computation that could lay the groundwork for applying quantum computing methods to protein structure prediction.

For decades, researchers have leveraged computational approaches to predict protein structures. A protein folds itself into a structure that determines how it functions and binds to other molecules in the body. These structures determine many aspects of human health and disease.

By accurately predicting the structure of a protein, researchers can better understand how diseases spread and thus how to develop effective therapies. Cleveland Clinic postdoctoral fellow Bryan Raubenolt, Ph.D. and IBM researcher Hakan Doga, Ph.D. spearheaded a team to discover how quantum computing can improve current methods.

In recent years, machine learning techniques have made significant progress in protein structure prediction. These methods are reliant on training data (a database of experimentally determined protein structures) to make predictions. This means that they are constrained by how many proteins they have been taught to recognize. This can lead to lower levels of accuracy when the programs/algorithms encounter a protein that is mutated or very different from those on which they were trained, which is common with genetic disorders.

The alternative method is to simulate the physics of protein folding. Simulations allow researchers to look at a given protein's various possible shapes and find the most stable one. The most stable shape is critical for drug design.

The challenge is that these simulations are nearly impossible on a classical computer, beyond a certain protein size. In a way, increasing the size of the target protein is comparable to increasing the dimensions of a Rubik's cube. For a small protein with 100 amino acids, a classical computer would need the time equal to the age of the universe to exhaustively search all the possible outcomes, says Dr. Raubenolt.

To help overcome these limitations, the research team applied a mix of quantum and classical computing methods. This framework could allow quantum algorithms to address the areas that are challenging for state-of-the-art classical computing, including protein size, intrinsic disorder, mutations and the physics involved in protein folding. The framework was validated by accurately predicting the folding of a small fragment of a Zika virus protein on a quantum computer, compared to state-of-the-art classical methods.

The quantum-classical hybrid framework's initial results outperformed both a classical physics-based method and AlphaFold2. Although the latter is designed to work best with larger proteins, it nonetheless demonstrates this framework's ability to create accurate models without directly relying on substantial training data.

The researchers used a quantum algorithm to first model the lowest energy conformation for the fragment's backbone, which is typically the most computationally demanding step of the calculation. Classical approaches were then used to convert the results obtained from the quantum computer, reconstruct the protein with its sidechains, and perform final refinement of the structure with classical molecular mechanics force fields.

The project shows one of the ways that problems can be deconstructed into parts, with quantum computing methods addressing some parts and classical computing others, for increased accuracy.

"One of the most unique things about this project is the number of disciplines involved," says Dr. Raubenolt. "Our team's expertise ranges from computational biology and chemistry, structural biology, software and automation engineering, to experimental atomic and nuclear physics, mathematics, and of course, quantum computing and algorithm design. It took the knowledge from each of these areas to create a computational framework that can mimic one of the most important processes for human life."

The team's combination of classical and quantum computing methods is an essential step for advancing our understanding of protein structures, and how they impact our ability to treat and prevent disease. The team plans to continue developing and optimizing quantum algorithms that can predict the structure of larger and more sophisticated proteins.

"This work is an important step forward in exploring where quantum computing capabilities could show strengths in protein structure prediction," says Dr. Doga. "Our goal is to design quantum algorithms that can find how to predict protein structures as realistically as possible."

In a new paper in Science Advances, researchers at JPMorgan Chase, the U.S. Department of Energy's (DOE) Argonne National Laboratory and Quantinuum have demonstrated clear evidence of a quantum algorithmic speedup for the quantum approximate optimization algorithm (QAOA).

This algorithm has been studied extensively and has been implemented on many quantum computers. It has potential applications in fields such as logistics, telecommunications, financial modeling and materials science.

"This work is a significant step towards reaching quantum advantage, laying the foundation for future impact in production," said Marco Pistoia, head of Global Technology Applied Research at JPMorgan Chase.

The team examined whether a quantum algorithm with low implementation costs could provide a quantum speedup over the best-known classical methods. QAOA was applied to the Low Autocorrelation Binary Sequences problem, which has significance in understanding the behavior of physical systems, signal processing and cryptography. The study showed that if the algorithm was asked to tackle increasingly larger problems, the time it would take to solve them would grow at a slower rate than that of a classical solver.

To explore the quantum algorithm's performance in an ideal noiseless setting, JPMorgan Chase and Argonne jointly developed a simulator to evaluate the algorithm's performance at scale.

"The large-scale quantum circuit simulations efficiently utilized the DOE petascale supercomputer Polaris located at the ALCF. These results show how high performance computing can complement and advance the field of quantum information science," said Yuri Alexeev, a computational scientist at Argonne. Jeffrey Larson, a computational mathematician in Argonne's Mathematics and Computer Science Division, also contributed to this research.

To take the first step toward practical realization of the speedup in the algorithm, the researchers demonstrated a small-scale implementation on Quantinuum's System Model H1 and H2 trapped-ion quantum computers. Using algorithm-specific error detection, the team reduced the impact of errors on algorithmic performance by up to 65%.

"Our long-standing partnership with JPMorgan Chase led to this meaningful and noteworthy three-way research experiment that also brought in Argonne. The results could not have been achieved without the unprecedented and world-leading quality of our H-Series Quantum Computer, which provides a flexible device for executing error-correcting and error-detecting experiments on top of gate fidelities that are years ahead of other quantum computers," said Ilyas Khan, founder and chief product officer of Quantinuum.

NXP, eleQtron and ParityQC Reveal First Quantum Computing Demonstrator For The DLR Quantum Computing Initiative - The Quantum Insider

Let's explore the high-stakes world of quantum computing. These three companies could change the future of computing, each in its own unique way.

Quantum computing may be the next big thing, and lots of people are talking about it. The potential to revolutionize industries from pharmaceuticals to finance has investors keeping a close eye on key players in this space.

But which companies are leading the charge?

To answer this critical question, a trio of Fool.com contributors with decades of high-tech analysis experience put their heads together and came up with three promising quantum computing stocks. Nvidia (NVDA -0.79%), IonQ (IONQ -2.98%), and D-Wave Quantum (QBTS -1.46%) offer very different approaches to the quantum market, but all three could make you a lot of money over the long haul.

So grab a coffee, sit back, and find out why these quantum computing stocks could be your next big investment.

Nicholas Rossolillo (Nvidia): I recently wrote a couple of articles about quantum computing and some breakthroughs happening in the nascent industry -- although "industry" is a bit generous. Quantum computing is more of a research and development initiative, not a full-blown industry.

Nevertheless, companies like Microsoftand start-up Quantinuum (majority-owned by Honeywell) have achieved incremental gains in quantum compute usefulness by pairing their quantum computers with classical computers. Why?

For one thing, the quantum mechanical measurements ("spooky" effects at the atomic level and smaller) are highly sensitive and prone to error. A tried-and-true classical computer can help correct those errors.

Thus, there may be no better classical computer right now than Nvidia's accelerated compute platform, powered by its GPUs and full stack of software libraries and artificial intelligence (AI) algorithms. In early spring 2023, Nvidia said it released a quantum computer control unit powered by its chips. And more recently, the company said multiple research supercomputers around the world have expanded their capabilities using Nvidia's CUDA-Q platform of GPUs and hybrid classical-quantum software algorithms.

And of course, Nvidia's latest Blackwell platform represents another exponential speed up in classical computing power. Researchers are already lining up for Blackwell to fuel their development of quantum, a potential "next big thing" at some point in the future.

To be clear, Nvidia's wild growth in the last year isn't because of quantum computing. This is but one of many applications developers are hard at work on, thanks to Nvidia GPUs. However, when trying to figure out a best place to invest today in the nascent quantum R&D initiative, Nvidia may be the simplest stock for most investors looking toward the future of the computing sector.

Whether quantum computers become a mainstream reality or not may actually largely depend on the pioneer of computing power today. I'm happy to keep holding my Nvidia shares, for quantum development and a lot of other tech breakthroughs too.

Billy Duberstein (IonQ): Quantum computing may seem like a speculative pie-in-the-sky bet. But quantum leader IonQ is actually making highly practical, tangible progress toward deploying quantum computing in real-world settings.

This has come down to the company's deliberate choices, such as deciding to use the mature technology of trapped ion qubits as the backbone of its current systems. While synthetically made qubits or alternatives may ultimately be faster or superior far down the road, these other technologies require temperatures near absolute zero to deploy, and have challenges that may not be overcome for years. On the other hand, atomic qubits can be deployed at room temperature and can run for longer periods of time.

The choice allows IonQ to sell systems to customers such as the U.S. Air Force Research Lab and QuantumBasel in Europe. Thus, the company generates revenue, and its adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) loss last quarter of $20.7 million seems manageable, given the company's cash pile of over $434 million.

Moreover, the company appears to be executing at a high level for the state of the business. Last quarter, even though the company only generated $7.6 million in revenue, IonQ beat its own revenue guidance, as it was able to recognize more revenue from a contract that was based on the completion of project milestones. And the company boosted its 2024 bookings guidance to a range of $75 million to $95 million, up from guidance of $70 million to $90 million one quarter ago.

This comes on the back of several technical achievements made earlier this year. These include reaching a working #AQ 35 system a year earlier than forecast in January, as well as achieving "ion-photon entanglements" in February, a technological achievement that will allow quantum systems to communicate with each other and scale quantum networks.

And the company also continues to attract top talent. In March, quantum algorithm expert Martin Roetteler joined IonQ from Microsoft and will head the company's efforts to develop real-world applications to run on IonQ's quantum computers. On the recent conference call with analysts, management noted its teams are making "serious headway" in advancing real-world quantum software applications.

I think IonQ's pragmatic and iterative approach is a good one, so that if quantum technology does manage to take off in the years ahead, it will likely be leading the pack.

Anders Bylund (D-Wave): I'm going way out on a limb here: D-Wave Quantum is about as risky as you can get in the quantum computing industry. It's a bona fide penny stock and barely large enough to talk about, with a market cap of just $200 million. The company is deeply unprofitable and its revenues skimpy, to the tune of merely $9.6 million over the last year.

So let's get real -- D-Wave is not a classic value investmentand too hot to touch for most growth investors, too. It's a speculative bet on the far future of quantum computing, and many things can go wrong along the way. Please keep your D-Wave investment small for now. If the company runs out of cash and goes out of business, make sure it doesn't hurt you.

But I'm talking about an established leader in the quantum computing sector here. It has produced actual systems with thousands of qubits. Its quantum software and consulting services are available on the Amazon Web Services Marketplace. And above all else, D-Wave holds hundreds of quantum computing patents and citations, second only to IBM in both cases.

D-Wave seems to be leaning away from the costly systems-building business for the moment. Instead, the company is focusing on monetizing its treasure trove of technology patents.

So maybe IonQ, IBM, or Nvidia will rule the world in terms of quantum computing hardware sales. Perhaps I haven't even heard of the sector's biggest long-term winner yet. But D-Wave looks poised to ride the coattails of whoever the final king might be, providing patent licenses and consulting services to unlock the full power of next-generation computers. These services should be in high demand in a few years.

And starting from this barely-there stock market footprint, D-Wave could be worth the risk. A small investment in this intriguing and incredibly low-priced stock may pay off handsomely as the quantum industry evolves.
