Chinese Scientists Report Using Quantum Computer To Hack Military-grade Encryption

schwit1 writes: Chinese scientists have mounted what they say is the world's first effective attack on a widely used encryption method using a quantum computer. The breakthrough poses a "real and substantial threat" to the long-standing password-protection mechanism employed across critical sectors, including banking and the military, according to the researchers.
Despite the slow progress in general-purpose quantum computing, which currently poses no threat to modern cryptography, scientists ha
