The Quantum Computing Race: USA Quest for Supremacy

2 Dec 2023

The Race for Quantum Supremacy

The field of quantum computing has advanced rapidly in recent years, with nations around the world investing heavily in research and development. At the forefront of this global technology race is the United States, which is pouring billions into the emerging quantum industry. The American government and technology companies hope to cement the nation's leadership in building the first supremely powerful quantum computers.

Quantum computers represent the next evolution in computational power. By leveraging the bizarre properties of quantum physics, they can carry out calculations beyond the scope of even the most advanced supercomputers today. A sufficiently advanced quantum computer could break current encryption standards, rapidly solve optimization problems like financial modeling or machine learning, or accurately simulate complex chemical and biological systems. Such capabilities would confer economic, technological, and national security advantages to whichever country controls this new computing paradigm first.

For the last 70 years, America has dominated technological innovation and reaped the benefits of that leadership. The advent of quantum computers poses an existential threat to this hegemony. As corporate giants and research institutions around the world tackle quantum, America strives to maintain its computing advantage in the 21st century through substantial investments in the emerging field.

The Quantum Gold Rush

In the year 2000, professor Richard Feynman first proposed using quantum effects for computation. While traditional computers encode information as bits represented by 0s and 1s, quantum computers utilize qubits which can represent 0 and 1 simultaneously during computation due to a phenomenon called superposition. By entangling multiple qubits together, an exponential increase in computational power can be achieved relative to classical machines.

In the early 2010s, researchers formulated procedures for error correction and fault-tolerant operation, making large-scale quantum computers appear economically feasible for the first time. With the theory solidified, the past five years have witnessed a flood of corporate interest and funding from America’s largest technology firms who hope to make commercially viable quantum hardware a reality.

Today, branches of the United States federal government also recognize the disruptive potential of quantum information systems. Government initiatives and partnerships with academia and industry have pushed progress to the point where rudimentary but functioning quantum computers with 50-100 qubits have been demonstrated in laboratory settings.

While no quantum computer today is sufficiently advanced to provide true supercomputing capabilities, rapid yearly advances in qubit count and quality encourage projections that practically useful machines will be available by 2030. Such systems may begin testing encryption protocols within the next decade. America funnels billions into quantum annually with the goal of crossing this threshold first and owning the landscape of security and computing for decades to come.

Corporations Lead the Charge

Well aware of quantum computing’s existential threat to modern cryptography and its boon for activities like financial analysis or chemistry simulation, Wall Street and Silicon Valley have entered into fierce competition over superior engineering talent and intellectual property.

With deep pockets and years of hardware development expertise, American tech giants are well positioned to shape early quantum hardware. Google, Microsoft, IBM, Intel, and startup ventures have invested billions into quantum laboratories and research partnerships across the United States. Smaller companies like Rigetti Computing, IonQ, and D-Wave have attracted hundreds of millions in investments as well.

Alphabet, Google’s parent company, leads private industry spending with investments in excess of $3 billion over the last few years. Their Google AI Quantum team has publicly demonstrated a 72-qubit system and has plans to exceed 1,000 error-corrected qubits this decade. Such capacity could allow rudimentary decryption of existing standards or begin economically meaningful sampling tasks.

Microsoft, for its part, has devoted over $1 billion to quantum projects and recently unveiled a subscription model for access to quantum computing over the internet. Their vision markets quantum capability as a cloud computing service which everyday developers can build upon. Cloud-based development tools and quantum programming languages will funnel research into direct commercial potential.

Not to be outdone, IBM and Amazon have each pledged over $200 million towards similar goals and provide quantum cloud access today. Startups like IonQ and Rigetti Computing have partnered with hyperscale cloud providers like Amazon Web Services to increase accessibility as well.

Intel, the semiconductor giant whose chips power most personal computers, has funneled approximately $50 million annually into quantum efforts like computer chip design as well as materials and fabrication research since 2015. Their integrated approach from high-level software down to quantum hardware itself gives the company outsized influence across the entire quantum stack.

With so much corporate investment focused on the engineering challenges, American companies currently dominate the international landscape in demonstrated qubit count and computer quality. Partnerships between industry and government steered through organizations like the National Quantum Initiative Office promise to maintain this leadership in the years ahead.

Academia Anchors the Ecosystem

While private companies jockey to make quantum advantage a commercial reality, America’s unparalleled higher education system provides a base of talented researchers, open discovery, and educated workers needed to feed quantum innovation.

University partnerships grant technology firms access to cutting-edge research like new computational algorithms, hardware architectures, and error correction techniques. Meanwhile, government grant programs allow university labs to tackle foundational research questions not driven by short-term profit motives. The knowledge and talent cultivated in academic settings permeates out towards practical industrial applications.

Hubs like the University of Southern California, Harvard, MIT, Berkeley, Caltech, University of Chicago, and University of Michigan anchor exceptionally strong regional quantum ecosystems on both coasts. Students arrive from across the country and the world to learn from globally renowned professors in quantum information science.

Upon graduation, American quantum researchers fill the ranks of national research laboratories like Los Alamos, Oak Ridge, Argonne, and Sandia which house some of the most advanced quantum computers in existence. Other graduates join startups commercializing new quantum technologies or are recruited into dedicated quantum efforts by computing giants.

America’s universities thus function as a critical launchpad that trains talent, circulates knowledge, and sparks new technologies to feed into both public initiatives and private sector applications. Sustained national investment keeps American academia at the forefront and attracts international students into the American quantum workforce.

Government Leadership in Science

Tracing its history to postwar scientific research for defense purposes, the United States government has long played a central role in advancing new technologies like computing, aerospace, telecommunications, and genetics. Quantum information science continues this tradition with substantial financial support and policy prioritization from Washington.

The roots of America’s dominance in quantum computing lead back to government programs at national laboratories in the 1990s. Today, specially designated National Quantum Information Science Research Centers coordinate efforts between government, academia, and industry. By selecting elite multidisciplinary teams for focused investment, their specialized facilities and research set technological goals for the wider quantum ecosystem.

Under the Trump and Biden administrations, bipartisan support led to the National Quantum Initiative Acts of 2018 and 2021 which authorized over $2.5 billion towards quantum priorities. The legislation formally establishes a 10-year plan to accelerate development of quantum for economic and national security purposes under an organized government strategy.

The law funnels research funds through the Department of Energy, National Science Foundation, National Institute of Standards and Technology, and White House Office of Science and Technology Policy among other bodies. New memorandums have prioritized quantum education, workforce development, commercialization, and hardware. Additional billions through defense programs remain classified but certainly pursue quantum applications relevant to intelligence agencies.

Complementing industry efforts, the Department of Energy plans a $1.8 billion dollar multi-lab bid to construct an exascale quantum computer by 2030. Meeting such an ambitious “Billion Qubit” vision would give America undisputed global leadership and confer immense power over computing dependent fields like artificial intelligence or materials design.

With China and the European Union racing to develop quantum technology backed by substantial state funding, American policymakers hope sustained investment will allow U.S. innovations to guide international standards and commercial markets.

The Road Ahead

Quantum computing has reached an inflection point where meaningful applications may become practical over the next decade. As the rest of the world pursues quantum capability, U.S. government, corporate, and academic initiatives strive to cement American leadership during this period.

The race is on and the winner may steer the course of innovation for decades to come. From Wall Street to Washington, America bets that its national computing prowess will reign supreme in the quantum future now fast approaching.
