Superconducting Quantum Computers: Leading the Race

Quantum computers, unlike classical ones, cannot correct errors by copying encoded data over and over. In the near term, quantum computers won’t run Shor’s, they’ll be small and run algorithms inspired by nature. Cryptography researchers have also begun preparing for quantum computers’ code-breaking capabilities.

The number of qubits determines the computer’s power and the algorithm complexity it can handle. However, scaling is difficult because neutral atom qubits, like all qubits, can lose their quantum state because of various factors such as unwanted laser light or magnetic fields. I had the opportunity to speak with Rob Hays, president and CEO of Atom Computing, about the new machine and the efforts that went into its development.

The Future of Quantum Computing

It’s honestly not terribly enlightening to follow the algebra through at this point – it’s a lot easier once certain other facts are known to you. But, again, if you’re feeling enthusiastic it’s a good exercise to work through to become familiar with how things work. The wire with the small, filled dot on it (the top wire, in this example) is called the control qubit, for reasons which will become clear in a moment.

This algorithm has important implications in the field of cryptography, as many encryption methods rely on the difficulty of factoring large numbers. Regular computers use bits, which are either ones or zeros, to process information. These bits are passed through logic gates, like AND, OR, NOT, and XOR, that manipulate the data and produce the desired output. These gates are made using transistors and are based on the properties of silicon semiconductors. While classical computers are efficient and fast, they struggle with problems that involve exponential complexity, such as factoring large numbers. Before large-scale quantum computers can be made, there are still a lot of fundamental problems that need to be solved.

One of the big learnings with the five-qubit machine was how to connect it to the LUMI supercomputer and how they could use a hybrid setup to hand off certain tasks from a supercomputer to a quantum device. Microsoft has laboratories and world-class researchers in any number of fields doing varied research. The new partnerships will build upon the Chicago area’s strengths in quantum science and engineering. The University of Chicago transformed the region’s quantum ecosystem more than a decade ago with the decision to make quantum technology a focus of the Pritzker School of Molecular Engineering.

While quantum computers are faster than traditional computers in performing multiple simulations, they hardly produce one correct answer to a question in a single run. Instead, quantum computing delivers probability distributions that we can understand as a range of results over multiple runs, which is the reason why quantum computers will not entirely replace classical computers. If the input is large or the output is large, e.g., event logs with billions of events in process mining applications, then it is probably infeasible to use quantum computing.

Quantum computers may have the potential to uproot some of our current systems. The cryptosystem known as RSA provides the safety structure for a host of privacy and communication protocols, from email to internet retail transactions. Current standards rely on the fact that no one has the computing power to test every possible way to de-scramble your data once encrypted, but a mature quantum computer could try every option within a matter of hours. They are not, however, presently “solving” climate change, turbocharging financial forecasting probabilities or performing other similarly lofty tasks that get bandied about in reference to quantum computing’s potential. QC may have commercial applications related to those challenges, but that’s well down the road.

Quantum Supremacy Using a Programmable Superconducting Processor

For those navigating the complexities of global freight, data is more than mere digital ink … Quantum computing promises to accelerate AI and could realistically compound the rapid shifts we’re already experiencing. That makes MSFT a strong bet and it offers much less risk than upstart firms in the space. The University of Chicago and IBM hope to expand the partnership to include Argonne National Laboratory and Fermilab National Accelerator Laboratory—both of which are members of the Chicago Quantum Exchange and home to two Department of Energy (DOE) quantum hubs.

Australian quantum strategy to build on unique science

Whether you are a software developer interested in quantum computing, or an expert who is highly proficient in quantum information theory, you’ll be able to gain a quantum speedup without the need to understand the underlying computational model. Our compiler automatically constructs quantum algorithms from classical code, so you can develop quantum algorithms for new domains without deep quantum expertise. Quantum computing could also help supercharge other critical technologies such as artificial intelligence that governments around the world are trying to rein in.

For example, certain mathematical results can legitimately be thought
of as no-go theorems for the purposes of foundational analysis, and
yet are not really relevant for the purpose of characterising the
class of efficiently simulable quantum phenomena. In this section we review the basic paradigm for quantum algorithms,
namely the quantum circuit model, which is composed of the basic
quantum units of information (qubits) and the basic logical
manipulations thereof (quantum gates). For more detailed introductions
see Nielsen and Chuang (2000) and Mermin (2007). Quantum computing is an area of computer science focused on the development of technologies based on the principles of quantum theory. Quantum computing uses the unique behaviors of quantum physics to solve problems that are too complex for classical computing. Error-prone but better than supercomputers at a cherry-picked task, quantum computers have entered their adolescence.

Quantum Computing Initiatives

“I believe we will do more in the next five years in quantum innovation than we did in the last 30,” says Gambetta. The University of Chicago leads efforts at the intersection of computer science, materials science and physics that have important implications for physics-informed software design. As quantum computers are scaled and interconnected with classical computing systems, the design of efficient software has the potential to significantly accelerate the performance and reliability of the new machines, shaving years off development time. The key to quantum computing is quantum algorithms – special algorithms uniquely constructed to take advantage of quantum properties, like quantum superposition and quantum entanglement. The properties of the quantum world allow for computations that would take billions of years on classical machines.

Google’s quantum computer in development, Sycamore, is said to have performed a calculation in 200 seconds, compared to the 10,000 years that one of the world’s fastest computers, IBM’s Summit, would take to solve it. IBM disputed Google’s claim, saying its supercomputer could solve the calculation in 2.5 days. The quantum state can be disturbed instantly by vibrations or temperature changes. This can cause qubits to fall out of superposition and cause errors to appear in computing. It’s important that qubits be protected from such interference by, for instance, supercooled refridgerators, insulation, and vacuum chambers.

He is the author of “The Entrepreneur’s Guide to the Art of War,” which Booklist called “Essential reading for the business leaders of tomorrow and a fascinating study of the boardroom as the new battlefield.” But despite the huge, theoretical computational power of quantum computers, there is no need to consign your old laptop to the wheelie bin just yet. Conventional computers will still have a role to play in any new era, and are far more suited to everyday tasks such as spreadsheets, emailing and word processing, according to Quantum Computing Inc. (QCI). However, the implications of quantum computing extend far beyond just financial gains. As West points out, the return on investment (ROI) for this disruptive technology has the potential to be transformative in scope, affecting not just individual industries but society as a whole. The promise rests in solving complex problems that to date have been insurmountable, from personalized medicine to sustainable energy solutions.
