Quantum computers could crack existing encryption methods Jvphoto/Alamy
Update: On 18 April, Yilei Chen announced an issue with his algorithm which he does not know how to fix. This means the algorithm does not undermine the mathematics behind post-quantum cryptography. The issue was found independently by researchers Hongxun Wu and Thomas Vidick.
An algorithm that could break supposedly future-proofed encryption methods has cryptographers scrambling to understand the threat, though there is no immediate danger of hackers gaining access to encrypted data.
Quantum computers threaten to one day crack the widely used encryption…
