# Quantum computers: what are they good for?

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.

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.

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.

## What Is Quantum Computing? Definition, Industry Trends, & Benefits Explained

“If anything is going to give something useful in the next five years, it will be chemistry calculations,” says Ronald de Wolf, senior researcher at CWI, a research institute for mathematics and computer science in Amsterdam. That’s because of the relatively low resource requirements, adds Shintaro Sato, head of the Quantum Laboratory at Fujitsu Research in Tokyo. “This would be possible using quantum computers with a relatively small number of qubits,” he says. Whatever the design, the clever stuff happens when qubits are carefully coaxed into ‘superposition’ states of indefinite character — essentially a mix of digital ones and zeroes, rather than definitely being one or the other.

Intel demonstrates exceptional yield of quantum dot arrays, showing promise for large-scale qubit production using transistor fabrication technology. This video is part of an “All Access” video series on the Intel Technology Channel featuring in-depth education and a look into key architectures that span the computing landscape. Watch this master class session to learn about how quantum computing is expected to be a world-changing technology. In contrast, quantum annealing begins with the traveler simultaneously occupying many coordinates thanks to the quantum phenomenon of superposition. Quantum tunneling allows the traveler to pass through hills—rather than be forced to climb them—reducing the chance of becoming trapped in valleys that are not the global minimum.

### The Journey to Building a True Quantum

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.

See how our industry experts prepare our clients to use this technology for competitive advantage. Quantum computers are elegant machines, smaller and requiring less energy than supercomputers. An IBM Quantum processor is a wafer not much bigger than the one found in a laptop.

### Do you need to be interested in quantum physics as a non-physicist?

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.

## Weird particle that remembers its past discovered by quantum computer

It is working with the Sussex researchers to develop machines that could help them design even better jet engines. “It is really difficult to say how close we are to the realisation of quantum computing, but I’m optimistic in how it can become relevant to us in our everyday lives.” Quantum particles can also be millions of miles apart and be strangely connected, mirroring each other’s actions instantaneously.

### What would a quantum computer be like in reality?

So, what are we to make of IBM’s new WatsonX solutions and Quantum Safe offerings? In fact, the company has been at the forefront of AI R&D since the 1950s with Arthur Samuels’ checkers-playing computer. IBM efforts continued through the Deep Blue system that beat chess grand master Gerry Kasparov in 1997 and the Watson system that triumphed over two Jeopardy grand champions in 2011. IBM also announced its Quantum Safe Roadmap, which is designed to help clients understand new threats and solutions and support them through this security transition. Watsonx.ai and watsonx.data are expected to be generally available in July 2023. Watsonx.governance is expected to be generally available later this year.

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.
