Inside the race to keep secrets safe from the quantum computing revolutionQuantum computers, however, use quantum bits known as “qubits” that can represent a zero, one, or both values simultaneously. The race to develop quantum safe encryption might not be well-known, but it’s crucially important. Without a new system of encryption, the secrets of governments and their citizens will spill out onto the internet. Security experts disagree on how long it will take – some say within five years, others a decade. The algorithms that have kept state secrets safe and confidential messages private since the 1970s are about to be broken. Classical computers rely on bits of data that must be either ones or zeroes. But they’re all convinced that it’s just a matter of years until it happens.
