The Looming Quantum Threat: NCSC Urges Encryption Upgrades

The danger to cryptography posed by next-generation large-scale, fault-tolerant quantum computers is widely understood. Although current encryption methods, which are used to secure everything from banking to communications, are based on mathematical algorithms that the everyday PC is unable to crack, a new era of incredibly fast quantum computers is just a few years away, poised to revolutionize problem-solving, communication, and computation.
