Quantum computing has enormous potential in healthcare and has started to impact the industry in various ways.

For example, quantum computing offers the ability to track and diagnose disease. Using sensors, quantum technology has the ability to track the progress of cancer treatments and diagnose and monitor such degenerative diseases as multiple sclerosis.

The tech also can help modernize supply chains. Quantum technology can solve routing issues in real time using live data such as weather and traffic updates to help determine the most efficient method of delivery. This would have been particularly helpful during the pandemic since many states had issues with vaccine deliveries.

Elsewhere, quantum technology can impact early-stage drug discovery. Pharmaceuticals can take a decade or longer to bring to market. Quantum computing could lower the costs and reduce the time.

"In the simplest terms, quantum computing harnesses the mysterious properties of quantum mechanics to solve problems using individual atoms and subatomic particles," explained Scott Buchholz, emerging technology research director and government and public services CTO at Deloitte Consulting. "Quantum computers can be thought of as akin to supercomputers.

"However, today's supercomputers solve problems by performing trillions of math calculations very quickly to predict the weather, study air flow over wings, etc.," he continued. "Quantum computers work very differently they perform calculations all at once, limited by the number of qubitsof information that they currently hold."

Because of how differently they work, they aren't well suited for all problems, but they're a fit forcertain types of problems, such as molecular simulation, optimization and machine learning.

"What's important to note is that today's most advanced quantum computers still aren't especially powerful," Buchholz noted.

"Many calculations they currently can do can be performed on a laptop computer. However, if quantum computers continue to scale exponentially that is, the number of qubitsthey use for computation continues to double every year or so they will become dramatically more powerful in years to come.

"Because quantum computers can simulate atoms and other molecules much better than classical computers, researchers are investigating the future feasibility of doing drug discovery, target protein matching, calculating protein folding and more," he continued.

"That is, during the drug discovery process, they could be useful to dramatically reduce the time required to sort through existing databases of molecules to look for targets, identify potential new drugs with novel properties, identify potential new targets and more."

Researchers also are investigating the possibility of simulating or optimizing manufacturing processes for molecules, which potentially could help make scaling up manufacturing easier over time. While these advances won't eliminate the lengthy testing process, they may well accelerate the initial discovery process for interesting molecules.

"Quantum computing may also directly and indirectly lead to the ability to diagnose disease," Buchholz said. "Given future machines' ability to sort through complex problems quickly, they may be able to accelerate the processing of some of the techniques that are being developed today, say those that are designed to identify harmful genetic mutations or combinations.

"Indirectly, some of the materials that were investigated for quantum computers turned out to be better as sensors," he added. "Researchers are investigating quantum-based technologies to make smaller, more sensitive, lower-power sensors. In the future, these sensors and exotic materials may be combined in clever ways to help with disease identification and diagnosis."

Quantum computers will improve the ability to optimize logistics and routing, potentially easing bottlenecks in supply chains or identifying areas of improvement, Buchholz said.

Perhaps more interestingly, due to their ability to simulate molecular interactions, researchers are looking at their ability to optimize manufacturing processes to be quicker, use less energy and produce less waste, he added. That could lead to alternative manufacturing techniques that could simplify healthcare supply chains, he noted.

"Ultimately, the promise of quantum computers is to make some things faster like optimization and machine learning and make some things practical like large scale molecular and process simulation," he said.

"While the technology to solve the 'at scale' problems is still several years in the future, researchers currently are working hard today to put the foundations in place to tackle these problems as the hardware capacity of quantum computers advances.

"Should the hardware researchers achieve some of the sought after scalability breakthroughs, that promise could accelerate," he concluded.

TOKYO IBM and the University of Tokyo have unveiled one of the most powerful quantum computers in Japan.

IBM Quantum System One is part of the Japan-IBM Quantum Partnership between the University of Tokyo and IBM to advance Japans exploration of quantum science, business, and education, according to IBM last month.

IBM Quantum System One is now operational for researchers at both scientific institutions and businesses in Japan, with access administered by the University of Tokyo.

IBM is committed to the growth of the global quantum ecosystem and fostering collaboration between different research communities, said Dr. Dario Gil, director, IBM Research.

The quantum computer gives users access to repeatable and predictable performance from high-quality qubits and high-precision control electronics, with quantum resources coupled with classical processing, according to IBM. Users can securely run algorithms requiring repetition of quantum circuits in the cloud.

The IBM Quantum System One in Japan is the second system of its kind by IBM to be built outside the U.S. In June, IBM unveiled an IBM Quantum System One in Munich, Germany, which is administered by Fraunhofer Geselleschaft, a scientific research organization.

IBMs quantum efforts are intended to help advance quantum computing and develop a skilled quantum workforce worldwide.

Gil is excited to see the contributions to research that will be made by Japans world-class academic, private sector, and government institutions.

Together, we can take major steps to accelerate scientific progress in a variety of fields, Gil said.

Teruo Fujii, president of the University of Tokyo, said that in the rapidly changing field of quantum technology, it is extremely important not only to develop quantum technology-related elements and systems, but also to foster the next generation of human resources in order to achieve advanced social implementation on a global scale.

Our university has a broad base of research talents and has been always promoting high-level quantum education from the undergraduate level. Now, we will further refine the development of the next generation of quantum native skill sets by utilizing IBM Quantum System One.

In 2020, IBM and the University of Tokyo launched the Quantum Innovation Initiative Consortium (QIIC), with the goal of strategically accelerating quantum computing research and development activities in Japan by bringing together academic talent from across the countrys universities, research associations, and industry.

In the last year, IBM has also announced partnerships that include a focus on quantum information science and technology with several organizations: the Cleveland Clinic, the U.K.s Science and Technologies Facilities Council, and the University of Illinois Urbana-Champaign.

Bitcoin and cryptocurrencies have seen a huge resurgence over the last year following the brutal so-called crypto winter that began in 2018.

The bitcoin price has this year climbed to never-before-seen highs, topping $60,000 per bitcoin before falling back slightly. Other smaller cryptocurrencies have risen at an even faster clip than bitcoin, with many making percentage gains into the thousands.

Now, as bitcoin and cryptocurrencies begin to carve out a place among traditional assets in investor portfolios, technologists have warned that advances in quantum computing could mean the encryption that underpins bitcoin is "fundamentally" undermined as soon as 2026unless the software is updated.

The bitcoin price has risen many hundreds of percent over the last few years but quantum computing ... [+] could spell the end of bitcoin and cryptocurrencies unless urgent action is taken.

"Quantum computers, expected to be operational by around 2026, will easily undermine any blockchain security systems because of their power," says the founder of quantum encryption company Arqit, David Williams, speaking over the phone. Arqit is gearing up for a September SPAC listing in New York.

"There needs to be rather more urgency," Williams adds.

Quantum computing, which sees traditional computer "bits" replaced with quantum particles (qubits) that can calculate information at vastly increased speed, has been in development since the 1990s. Researchers at universities around the world are now on the verge of creating a working quantum computer, with search giant Google and scientists from the University of New South Wales in Sydney, Australia, recently making headlines with breakthroughs.

Williams, pointing to problems previously identified by the cofounder of ethereum and creator of cardano, Charles Hoskinson, warns that upgrading to post-quantum algorithms will "dramatically slow blockchains down" and called for blockchain developers to adopt so-called quantum encryption keys.

"Blockchains are effectively fundamentally flawed if they dont address the oncoming quantum age. The grownups in the room know what's coming."

Others have also begun working on getting bitcoin and other blockchains ahead of quantum computing.

"If this isn't addressed before quantum computers pose a threat, the impact would be massive," says Duncan Jones, head of quantum cybersecurity at Cambridge Quantum Computing, speaking via email. "Attackers could create fraudulent transactions and steal currency, as well as potentially disrupting blockchain operations."

Earlier this month, Cambridge Quantum Computing, along with the Inter-American Development Bank and Tecnolgico de Monterrey, identified four potential threats to blockchain networks posed by quantum computers and used a post-quantum cryptography layer to help protect them.

"Time is of the essence here," says Jones, pointing to Google chief executive Sundar Pichai's prediction that encryption could be broken in as little as five to 10 years. "It's important for decentralized networks to start this migration process soon because it requires careful planning and execution. However, I'm hopeful the core developers behind these platforms understand the issues and will be addressing them."

Recently, it's been reported that China is pulling ahead in the global quantum race, something Williams fears could undermine both traditional and crypto markets to the same degree as the 2008 global financial crisis.

"On day one, the creation of a quantum computer doesn't break everything," says Williams. "It will probably initially happen in secret and the information will slowly leak out that the cryptography has been broken. Then there will be a complete loss of confidence, similar to how the global financial crisis saw confidence in the system disintegrate."

With more than 11,000 different cryptocurrencies now listed on crypto data website CoinMarketCap and competition between bitcoin and other major cryptocurrencies reaching fever pitch, adding protection against the coming quantum revolution could be beneficial.

"If anyone one blockchain company could deliver proof it's quantum-safe it would have an advantage," says Williams.

Urgent Warning Issued Over The Future Of Bitcoin Even As The Crypto Market Price Smashes Past $2 Trillion - Forbes

Youre probably quite familiar with the basic states of mattersolid, liquid, gasthat fill everyday life on Earth.

But those three different sorts of matter that each look and act differently arent the whole of the universefar from it. Scientists have discovered (or created) dozens of more exotic states of matter, often bearing mystical and fanciful names: superfluids, Bose-Einstein condensates, and neutron-degenerate matter, to name a few.

In the last few years, physicists around the world have been constructing another state of matter: a time crystal. If that seems like B-movie technobabble, its technobabble no longer. Using a quantum computer, a few researchers have created a time crystal that, they think, firmly establishes time crystals in the world of physics.

The researchers havent yet formally published their research, but last month, they posted a preprint (a scientific paper that has yet-to-be peer-edited) on the website ArXiV.

So what exactly is a time crystal? It might sound like the critical component that makes a time machine tick, some sort of futuristic power source, or perhaps an artifact of a lost alien civilization. But, to scientists, a time crystal is actually something more subtle: a curiosity of the laws of physics.

What defines any bog-standard crystalsuch as a diamond, an emerald, or even an ice cubeis that the crystals atoms are somehow arranged in repeating patterns in space. Theres three dimensions of spaceand a fourth dimension, time. So physicists wondered if a crystals atoms could be arranged in repeating patterns in time.

In practice, that works something like this. You create a crystal whose atoms start in one state. If you blast that crystal with a finely tuned laser, those atoms might flip into another stateand then flip backand then flip againand so forth, all without actually absorbing any energy from the laser.

If you step back, what youve just created is a state of matter thats perpetually in motion, indefinitely, without taking in any energy.

Thats no small feat. It beats against one of classical physics most sacred tenets: the second law of thermodynamics. That law states that the amount of entropy, or disorder, always tends to increase. Think of it like a vase, teetering at the edge of a table. The universe wants to push that vase over and make it shatter across the floor. To piece it back together, you have to put in the energy.

Time crystals are actually a rather new idea, having first been theorized by Nobel-winning physicist Franck Wilczek in 2012. Not all physicists accepted that theory at the time, with some claiming that the second law of thermodynamics would rear its legalistic head.

Naturally, determined researchers found loopholes. In 2016, physicists at the University of Maryland managed to bodge together a crude time crystal from a collection of ytterbium atoms. Other groups have created time crystals inside diamonds.

But these latest time-crystal-tinkerers did something different. They turned to Google and used a quantum computer: a device that takes advantage of the quirks of quantum mechanics, the seemingly mystical sort of physics that guides the universe at the tiniest scales. Instead of using bits of silicon like everyday, classical computers, quantum computers operate directly with atoms or particles. That allows physicists to do experiments which can be agonizingly difficult with traditional computers, since quantum physicswhich allows particles to be multiple things at one and for particles to interact at seemingly impossible distancesgets quite esoteric.

The ability to simulate the rulesbecomes so much harder with traditional computers, says Gabriel Perdue, a quantum computer researcher at Fermilab, a national lab in suburban Chicago that focuses on high-end particle physics.

But, by arranging particles in a quantum computers processor, its possible to literally study systems of tiny particles as if they are building blocks. Thats a powerful ability, and its not something youll see much in the non-quantum world.

We dont compute, you know, how far a baseball goesby building miniature baseball players and doing simulations, says Perdue. But doing something quite similar on a very small scale, he says, is what the researchers used Googles quantum computer to do to make their time crystal.

In this case, physicists could take atoms, rearrange them, then pulse them with a laser to drive a time crystal. That setup has allowed researchers to create a time crystal thats bigger than any time crystal before it. While many previous time crystals were short-lasting and unravelled within a few back-and-forth flip cycles, the scientists behind this latest time crystal effort are marvelling at the stability of what theyve created.

The thing that is most exciting here, for me, says Perdue, its a demonstration of using a quantum computer to really simulate a quantum physics system and study it in a way that is really novel and exciting.

So, could these time crystals indeed lead to a new wave of nascent time machines?

Probably not. But they might help make quantum computers become more robust. Engineers have struggled for years to create something that could serve as memory in quantum computers; some equivalent to the silicon that underpins traditional computers. Time crystals, physicists think, could serve that purpose.

And this experiment, Perdue says, is also a demonstration of the power of quantum computers to do science. The same platform that makes it easy for you to simulate some cool algorithm, he says, works just as well, and I would argue even better, for simulating these kinds of systems.

Since receiving a $25 million grant in 2019 to become the first National Science Foundation (NSF) Quantum Foundry, UC Santa Barbara researchers affiliated with the foundry have been working to develop materials that can enable quantum informationbased technologies for such applications as quantum computing, communications, sensing, and simulation.

They may have done it.

In a new paper, published in the journal Nature Materials, foundry co-director and UCSB materials professor Stephen Wilson, and multiple co-authors, including key collaborators at Princeton University, study a new material developed in the Quantum Foundry as a candidate superconductor a material in which electrical resistance disappears and magnetic fields are expelled that could be useful in future quantum computation.

A previous paper published by Wilsons group in the journal Physical Review Letters and featured in Physics magazine described a new material, cesium vanadium antimonide (CsV3Sb5), that exhibits a surprising mixture of characteristics involving a self-organized patterning of charge intertwined with a superconducting state. The discovery was made by Elings Postdoctoral Fellow Brenden R. Ortiz. As it turns out, Wilson said, those characteristics are shared by a number of related materials, including RbV3Sb5 and KV3Sb5, the latter (a mixture of potassium, vanadium and antimony) being the subject of this most recent paper, titled Discovery of unconventional chiral charge order in kagome superconductor KV3Sb5.

Materials in this group of compounds, Wilson noted, are predicted to host interesting charge density wave physics [that is, their electrons self-organize into a non-uniform pattern across the metal sites in the compound]. The peculiar nature of this self-organized patterning of electrons is the focus of the current work.

This predicted charge density wave state and other exotic physics stem from the network of vanadium (V) ions inside these materials, which form a corner-sharing network of triangles known as a kagome lattice. KV3Sb5 was discovered to be a rare metal built from kagome lattice planes, one that also superconducts. Some of the materials other characteristics led researchers to speculate that charges in it may form tiny loops of current that create local magnetic fields.

Materials scientists and physicists have long predicted that a material could be made that would exhibit a type of charge density wave order that breaks what is called time reversal symmetry. That means that it has a magnetic moment, or a field, associated with it, Wilson said. You can imagine that there are certain patterns on the kagome lattice where the charge is moving around in a little loop. That loop is like a current loop, and it will give you a magnetic field. Such a state would be a new electronic state of matter and would have important consequences for the underlying unconventional superconductivity.

The role of Wilsons group was to make the material and characterize its bulk properties. The Princeton team then used high-resolution scanning tunnelling microscopy (STM) to identify what they believe are the signatures of such a state, which, Wilson said are also hypothesized to exist in other anomalous superconductors, such as those that superconduct at high temperature, though it has not been definitively shown.

STM works byscanninga very sharp metal wire tip over a surface. By bringing the tip extremely close to the surface and applying an electrical voltage to the tip or to the sample, the surface can be imaged down to the scale of resolving individual atoms and where the electrons group. In the paper the researchers describe seeing and analyzing a pattern of order in the electronic charge, which changes as a magnetic field is applied. This coupling to an external magnetic field suggests a charge density wave state that creates its own magnetic field.

This is exactly the kind of work for which the Quantum Foundry was established. The foundrys contribution is important, Wilson said. It has played a leading role in developing these materials, and foundry researchers discovered superconductivity in them and then found signatures indicating that they may possess a charge density wave. Now, the materials are being studied worldwide, because they have various aspects that are of interest to many different communities.

They are of interest, for instance, to people in quantum information as potential topological superconductors, he continued. They are of interest to people who study new physics in topological metals, because they potentially host interesting correlation effects, defined as the electrons interacting with one another, and that is potentially what provides the genesis of this charge density wave state. And theyre of interest to people who are pursuing high-temperature superconductivity, because they have elements that seem to link them to some of the features seen in those materials, even though KV3Sb5 superconducts at a fairly low temperature.

If KV3Sb5 turns out to be what it is suspected of being, it could be used to make a topological qubit useful in quantum information applications. For instance, Wilson said, In making a topological computer, one wants to make qubits whose performance is enhanced by the symmetries in the material, meaning that they dont tend to decohere [decoherence of fleeting entangled quantum states being a major obstacle in quantum computing] and therefore have a diminished need for conventional error correction.

There are only certain kinds of states you can find that can serve as a topological qubit, and a topological superconductor is expected to host one, he added. Such materials are rare. This system may be of interest for that, but its far from confirmed, and its hard to confirm whether it is or not. There is a lot left to be done in understanding this new class of superconductors.
