A “useless” algorithm that serves as a reference point to demonstrate the power of quantum computers on ordinary devices could be reused as a way of maintaining safe data from quantum computers.
Quantum computers have long threatened to decipher existing encryption algorithms, which depend on problems that are difficult to solve for classic computers, such as finding the prime factors of a large number. A large quantum computer could do this, but Bill Fefferman At the University of Chicago, Illinois and his colleagues Let’s say the devices could also …
