ABSTRACT

Quantum Information Science: Applications, Global Research and Development, and Policy Considerations [November 19, 2018]   [open pdf - 1MB]

"Combining elements of mathematics, computer science, engineering, and physical sciences, quantum information science (QIS) has the potential to provide capabilities far beyond what is possible with the most advanced technologies available today. Quantum science, generally, is the study of the smallest particles of matter and energy; QIS builds on quantum science principles to obtain and process information in ways that cannot be achieved based on classical physics principles. QIS is based on the premise that information science depends on quantum effects in physics. The advantages to using QIS in certain circumstances can be illustrated by the example of quantum computing. Quantum computing is not just 'faster' than classical computing. It is not useful for many types of problems where a classical supercomputer would excel. However, there are certain tasks for which the power of quantum computing is unmatched, such as code breaking. This power is derived from quantum computing's use of 'qubits' or 'quantum bits.'"
