While the rest of the country has been transfixed by the Brett Kavanagh confirmation drama, the White House was quietly but steadily taking major steps to secure America鈥檚 high-tech future.
The first was the release of the National Cybersecurity Strategy last week, which I discussed in a previous This week came the National Strategic Overview for Quantum Information Science (QIS), released by a subcommittee of the Committee on Science for the National Science and Technology Council. This document is a big win for Jacob Taylor, the White House Office of Science and Technology Policy鈥檚 point man on all things quantum, and a major win for America.
At last we have a plan that brings real government-level coordination for advancing the technology that will result in a major revolution in how we live in the 21st century.
Let鈥檚 remember that while a traditional computer has to sequentially explore the potential solutions to a mathematical problem, a quantum system is able to look at every potential solution simultaneously and generate answers鈥攏ot just the single 鈥渂est鈥� but nearly ten thousand close alternatives as well鈥攊n less than a second.
This means myriad problems that are currently insoluble for digital computers, even the fastest supercomputers, will be solved by a future quantum computer. This promises to lead to major breakthroughs in areas like medicine, material science, and climate science. Through quantum sensing scientists will even be able to perform the equivalent of seeing through steel walls and probing the deepest depths of the sea.
This is why the committee鈥檚 twenty-page report asserts that leading the way in QIS is a matter of national security but also economic security, as quantum technology fuels for a new high-tech industrial revolution for the U.S. and for the rest of the world.
In the document鈥檚 own words, the plan focuses 鈥渙n a science-first approach鈥� that aims to identify and solve the big challenges America will face in embracing this transformative technology, while also building 鈥渁 quantum-smart and diverse workforce to meet the needs of a growing field鈥� and encouraging 鈥渋ndustry engagement, providing appropriate mechanisms for public-private partnerships.鈥�
At the same time, the plan calls on government to 鈥減rovide the key infrastructure and support needed to realize the scientific and technological opportunities鈥� that will be coming in the quantum revolution.
There鈥檚 lots to applaud in this plan. There鈥檚 the recognition that winning the race for a quantum computer will require strong international cooperation, including with our closest allies鈥攁 cause to which our Quantum Alliance Initiative here at the 华体会 has been committed since our founding.
As noted, the plan also recognizes the need to develop a strong quantum workforce to sustain American leadership in the quantum arena for the long-term future. 鈥淕rowing an American quantum-smart workforce with expertise in a broad range of physical information, and engineering sciences is crucial for assuring sustained progress in QIS,鈥� it correctly argues. Therefore, the plan mandates government agencies like the National Science Foundation to focus on expanding programs that will further that goal, adding, 鈥渦niversities should be encouraged to address the workforce development needs by adding tenured or tenure-track faculty within the interdisciplinary themes associated with QIS and consider Quantum Science and Engineering as a discipline for future concentration.鈥�
There鈥檚 also one other issue that this plan doesn鈥檛 directly address. Unfortunately, among the complicated puzzles future quantum computers will be able to solve are the math-based algorithms that protect our public encryption systems.
Experts agree that the new possibilities arising from quantum computing will create a mortal threat to today鈥檚 IT security. An algorithm formulated by mathematician Peter Shor in 1994 demonstrated that quantum computers will be able to factor large numbers far more efficiently than classical computers. Making large-number factoring all but impossible is the foundation for most of today鈥檚 encryption standards.
The coming years will witness the advent of a quantum computer powerful enough to break the encryption techniques currently used billions of times every day.
I agree with the 鈥渟cience-first鈥� approach to quantum information science is necessary if we are going to win the quantum race. But it鈥檚 not sufficient by itself. We also need to focus a broad-based national effort on finding ways to develop post-quantum cryptographic methods; and to use quantum technology itself to render our most vital public and private data and networks essentially unhackable.
These are already underway in our leading government security agencies, including at the National Security Agency and the Department of Commerce鈥檚 National Institute for Standards and Technology. There are also important efforts underway by private companies in the U.S. and around the world, including by allies like Canada and Australia. Now we need a major national effort for securing critical data and networks before a quantum computer powerful enough to decrypt current systems is realized.
So, here鈥檚 three cheers for the National Strategic Overview on quantum-and three cheers for the National Strategic Overview on quantum cybersecurity that still needs to be done.
