“NSA does not know if or when a quantum computer of sufficient size to exploit public key cryptography will exist.
The cryptographic systems that NSA produces, certifies, and supports often have very long life-cycles.
But groups from Canada, Japan, Italy and Singapore also have plans for quantum space experiments.
“Definitely, I think there will be a race,” says Chaoyang Lu, a physicist at the University of Science and Technology of China in Hefei, who works with the team behind the Chinese satellite.
NSA believes the time is now right—consistent advances in quantum computing are being made, there are many more proposals for potentially useful quantum resistant algorithms than were available 5 years ago, and the mandatory change to elliptic curves that would have been required in October 2015 presented an opportune time to make an announcement.
