Report from the Congressional Research Service: “Quantum information science (QIS) combines elements of mathematics, computer science, engineering, and physical sciences, and has the potential to provide capabilities far beyond what is possible with the most advanced technologies available today.
Although much of the press coverage of QIS has been devoted to quantum computing, there is more to QIS. Many experts divide QIS technologies into three application areas:
- Sensing and metrology,
- Communications, and
- Computing and simulation.
… Today, QIS is a component of the National Strategic Computing Initiative (Presidential Executive Order 13702), which was established in 2015. Most recently, in September 2018, the National Science and Technology Council issued the National Strategic Overview for Quantum Information Science. The policy opportunities identified in this strategic overview include:
- choosing a science-first approach to QIS,
- creating a “quantum-smart” workforce,
- deepening engagement with the quantum industry,
- providing critical infrastructure,
- maintaining national security and economic growth, and
- advancing international cooperation.
This report provides an overview of QIS technologies: sensing and metrology, communications, and computing and simulation. It also includes examples of existing and potential future applications; brief summaries of funding and selected R&D initiatives in the United States and elsewhere around the world; a description of U.S. congressional activity; and a discussion of related policy considerations….(More)”.
