# Quantum breakthrough could revolutionise computing

When scientists and engineers encounter difficult problems, they turn to supercomputers. These are very large classical computers, often with thousands of classical CPU and GPU cores. However, even supercomputers struggle to solve certain kinds of problems.

It is a Lewis Carroll-like place where ghostly particles pop in and out of existence, swirling electrons occupy two positions at once, and objects possess dual natures — they can be both waves and particles simultaneously. But startup difficulties wouldn’t cause a quantum winter, Quantinuum Chief Operating Officer Tony Uttley believes. Two scenarios that could trigger a winter, though, are if a big quantum computing company stopped its investments or if progress across the industry stalled, he said. Keeping up with technology roadmaps is critical for startups, said Duncan Stewart of the Business Development Bank of Canada, which has invested in quantum computing startups. One of them, Nord Quantique in Quebec, “will live or die based on whether they meet their technical milestones 18 months from now,” he said.

## What is a quantum computer? Explained with a simple example.

One is more stable, the second has a higher fidelity, and others are more easily mass-produced. Under the right circumstances, the increase in qubits means the system can store and process exponentially more information than the classical bits on which standard computers run. Universal quantum computers can be used to solve a wide range of problems.

Canada’s University of Waterloo is one of the best well-known universities for quantum computing due to its Institute for Quantum Computing. With over 29 faculty members and 300 researchers, their quantum computing Ph.D. program works to train the next generation of the quantum workforce through global collaborations involving other universities, organizations, and quantum companies. Stanford University has multiple researchers studying quantum computing, including the Q-Farm, an acronym standing for Quantum Fundamentals, Architectures, and Machine learning initiative. Q-Farm collaborates with Stanford’s national acceleration Laboratory (SLAC) to develop answers to some of the biggest challenges for quantum computing. The University of Maryland’s JQI offers a unique experience for students, as it includes quantum scientists from the National Institute of Standards and Technology (NIST), the University of Maryland, and the Laboratory for Physical Sciences (LPS). With this diversity in researchers, students have a wide range of quantum degree programs to choose from, including theoretical and experimental quantum physics.

Along with its work on three of the four quantum-resistant algorithms adopted for standardization by the NIST, IBM also embedded quantum safe features in the z16 mainframes and LinuxONE 4 systems it launched last year. While some quantum computing and quantum-like solutions are available, the market is still in very early days. However, potential dangers lie ahead as quantum technologies mature and become increasingly available to valid business and government agencies, as well as to bad actors, including rogue states and organized cybercriminals. Researchers from QuTech improved the so-called “Andreev spin qubit” in a critical way and believe it can become a prime candidate in the pursuit of a perfect qubit. The new type of qubit is created in a more reliable and intrinsically stable way, compared to previous versions, by combining the advantages of two other types of qubits. What started the hype, and is in some way still driving it, is an algorithm for quantum computers that Peter Shor, an American mathematician and professor at MIT, developed in 1994.

His start-up company, Universal Quantum in Haywards Heath, UK, is now working with engineering firm Rolls-Royce in London and others to begin the long and arduous process of building it. “I’m not trying to take away from how much work there is to do, but we’re surprising ourselves about how much we’ve done,” says Jeannette Garcia, senior research manager for quantum applications and software at technology giant IBM in San Jose, California. Some properties of quantum computers can be imitated with sound trapped in a simple mechanical device.

### Will I get a quantum computer at home?

For calculations that are limited in scope, classical computers are still the preferred tools. But for very complex problems, quantum computers can save time by narrowing down the range of possible answers. When classical computers solve a problem with multiple variables, they must conduct a new calculation every time a variable changes. Quantum computers, however, have a larger working space, which means they can explore a massive number of paths simultaneously. This possibility means that quantum computers can be much, much faster than classical computers.

## Why is there so much hype about the quantum computer?

The ability of a quantum computer to surpass the fastest conventional machine is known as “quantum supremacy,” a phrase coined by physicist John Preskill in 2012. Even in conventional computing, proving that your algorithm beats mine isn’t straightforward. You must pick a task that represents a fair test and choose valid methods of measuring speed and accuracy. The outcomes of tests are also prone to misinterpretation and confirmation bias. “What’s new,” Aaronson wrote, “is that millions of dollars are now potentially available to quantum computing researchers, along with equity, stock options, and whatever else causes ‘ka-ching’ sound effects and bulging eyes with dollar signs.

## Scrambling and quantum teleportation

Among others, Honeywell Quantum Solutions merged with Cambridge Quantum to form Quantinuum in 2021; Pasqal merged with Qu&Co in 2022; and ColdQuanta — newly renamed Infleqtion — acquired Super.tech. Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. After I read Q Is for Quantum, Rudolph patiently answered my questions about it. You can find our exchange (which assumes familiarity with the book) here. He also answered my questions about PsiQuantum, the firm he co-founded in 2016, which until recently has avoided publicity. Although he is wittily modest about his talents as a physicist (which adds to the charm of Q Is for Quantum), Rudolph is boosterish about PsiQuantum.

Tossing 2 coins offers 4 different combinations of heads and tails (HH, HT, TH, and TT) but tossing 3 coins allows for 8 distinct combinations (HHH, HHT, HTT, HTH, THT, THH, TTH, and TTT). Quantum computers will be able to tackle certain types of problems — especially those involving a daunting number of variables and potential outcomes, like simulations or optimization questions — much faster than any classical computer. This is a strange way to think, but it is one of the correct ways to interpret how the qubits behave in the real world. Similarly, if you set all three qubits to both 0 and 1, you’d be creating 8 parallel worlds — 000, 001, 010, 011, 100, 101, 110, and 111. With a regular computer, using 3 bits, we were able to represent only one of these solutions at a time — for example, 001. To solve this problem with a regular, non-quantum computer, you’ll need first to figure out how to store the relevant information with bits.

In situations where there are a large number of possible combinations, quantum computers can consider them simultaneously. Examples include trying to find the prime factors of a very large number or the best route between two places. Classical computers, which include smartphones and laptops, encode information in binary “bits” that can either be 0s or 1s. In a quantum computer, the basic unit of memory is a quantum bit or qubit.

The laboratory offers several different projects to work on, all with real-world applications. Quantum theory is a revolutionary advancement in physics and chemistry

that emerged in the early twentieth century. It is an elegant

mathematical theory able to explain the counterintuitive behavior of

subatomic particles, most notably the phenomenon of entanglement. In

the late twentieth century it was discovered that quantum theory applies

not only to atoms and molecules, but to bits and logic operations in a

computer. This realization has brought about a revolution in the

science and technology of information processing, making possible kinds

of computing and communication hitherto unknown in the Information Age.

They further define that software and firmware signing should begin transitioning immediately. With the emergence of any new, potentially groundbreaking technology, there’s always an accompanying level of public excitement on what it’ll bring from the get-go. For certain use cases, such as encryption/decryption and quantum ML, that hype is proving true, but only within the realms of particular contexts, according to Healy.
