How quick an Google get their Quantum gizmo going and render security obsolete?
They haven’t. . . even if their quantum computers were 100 trillion times faster than today’s fastest supercomputers which would take an estimated 5.26 X 10195 years to try every possible key to a current 256 bit AES encrypted file, it would only shorten the time to an estimated 5.26 X 10181 years to do the same thing using the quantum computer. That’s the law of very large numbers at work. . . and cryptologists can always move to 512, 1024, 2048, or even 4096 Advanced Encryption Standard (AES) using a Quantum computer to do the encryption. . .
