Once considered a scientific impossibility, quantum computing is now expected to have a far-reaching commercial impact thanks to an increase in investment and a myriad of new discoveries by physicists and computer scientists. Quantum computers have the potential to transform industries from auto manufacturing to pharmaceuticals to finance, but the technology has only recently moved from the laboratory to the commercial market.

At the Consumer Electronics Show in Las Vegas in January, IBM Corp. announced it had struck partnerships with Daimler AG (the parent company of Mercedes-Benz) and Delta Air Lines Inc. to harness quantum computing to solve real-world issues for the two companies. Advancing electric vehicle batteries and improving route scheduling could be some of the first commercial applications for the nascent technology.

Quantum Computing 101

Quantum computing marries the properties of quantum physics with advanced computer science, creating a potent combination that is immensely more powerful than classical computing. While classical computer algorithms scale exponentially, quantum computers scale polynomially. This leads to huge advantages in time, accuracy, and processing capability.

Ordinary classical computers perform calculations using "bits" of information in the form of 0s and 1s, while quantum computers use quantum bits, or qubits, that can simultaneously exist as both a 0 and a 1. In the quantum universe, a flipped coin can exist as both heads and tails. Qubits have the power to vastly increase the predictive powers of quantum computers, allowing them to solve complex equations that could take a classical computer thousands of years to solve, if solvable at all.

The Future Is Now

In October 2019, Google Inc. published an article in the journal Nature detailing how its quantum computer performed a complex computation in 200 seconds that they claim would have taken the most powerful supercomputer some 10,000 years (a magnitude of 1.5 trillion times faster). With this, Google achieved what it called "quantum supremacy" — the successful demonstration that a programmable quantum device can solve a problem that classical computers practically cannot. In the article announcing Google's breakthrough, researchers stated that "we are only one creative algorithm away from valuable near-term application."

IBM's announcement shows that real-world applications are already upon us. Jamie Thomas, general manager of systems strategy and development for IBM, hailed the partnerships: "[Daimler and Delta] join more than 100 clients already experimenting with commercial quantum computing ... to tackle problems like risk analytics and option pricing, advanced battery materials and structures, manufacturing optimization, fraud detection, chemical research, logistics and more."

The promise of this technology is great, and there is a sense within the computing industry that we are entering a period of time where the technology and its possibilities will develop rapidly. IBM's director of research, Dario Gil, stated that "this is the most exciting time in computing in many decades" and claims that by the end of the decade we will reach a point of "Quantum Advantage," the exploitation of quantum computing for scientific and commercial advantage.

Amazon.com Inc. recently set up its AWS Center for Quantum Computing at Caltech that will leverage academic-commercial partnerships to accelerate development of quantum computing hardware and software. The e-commerce giant has also begun offering its cloud users the ability to experiment with quantum computing via Amazon Web Services. Similarly, Microsoft Corp. provides access to quantum processes via its Azure cloud service.

IBM has created its "Q Network," a cloud-based setup that provides access to the company's quantum computing hardware, software and developer tools. This was the fourth year in a row IBM doubled the quantum volume of their computers. Currently, 15 IBM quantum computers are powering over 200,000 users and the now 100 commercial partners announced at the Consumer Electronics Show.

In December 2018, President Donald Trump signed the National Quantum Initiative Act, which allocates $1.2 billion to advance research and development of quantum technologies. The president's budget proposal announced in February includes a proposal to spend $25 million on what it calls a national "quantum internet," a network of machines designed to make it harder to intercept digital communication. The administration also vowed to double funding for artificial intelligence and quantum computing research outside the U.S. Department of Defense by 2022.

Meanwhile, China has developed a new quantum research facility worth $10 billion in addition to a dedicated quantum communication network between Beijing and Shanghai, costing some $80 million. The European Union has developed a $1.1 billion quantum master plan.

The Technological and Commercial Opportunities

The power of quantum computers could change the research and creation of products as diverse as antibiotics, polymers for lightweight airplanes, electronic materials, electrolytes for next generation batteries, and more. Quantum computers also have the computational power to solve complex optimization issues for logistics and transportation companies that previously were insurmountable.

Accenture PLC, for example, is currently examining ways in which quantum computers can tackle specific business problems such as finding the ideal route for retail deliveries and optimizing machine learning. Given this, it is not surprising that a growing number of companies are exploring the benefits of quantum computing.
