New Cryptography Must Be Developed and Deployed Now, Even Though a Quantum Computer That Could Compromise Today’s Cryptography Is Likely at Least a Decade Away, Says New Report

National Academies  December 4, 2018
According to a NAS [Open Access] report  it is still too early to be able to predict the time horizon for a practical quantum computer. The current research on quantum computing has clear implications for national security. Any entity that has a large-scale quantum computer could break today’s cryptography to read intercepted communications or stored data. Continued support from the U.S. to this field is imperative if the country wants to maintain its leadership position…read more.
