I believe that quantum computers are probably being used now to break today’s encryption secrets. I’m not normally a conspiracy theorist, so let me tell you why I think this is true.
Ever since Peter Shor released a quantum algorithm in 1994 that proved quantum computers with enough quantum bits (qubits) could easily break most popular public key cryptography (e.g., RSA, Diffie-Hellman, Elliptic Curve), we’ve all been waiting for the day when that occurs. It’s generally known as the “quantum crypto break.”
