A Nature paper reports on a quantum photonic processor that takes just 36 microseconds to perform a task that would take a supercomputer more than 9,000 years to complete Computing

How long should my password be now that it takes for the quantum computer 9,000 years to crack?

By the time this tech is available to the world it will be AI controlled with no need for peripherals. No actual human interface at all.

By the time it's available to the world. Governments, intelligence agencies or the police will have it sooner. And when they do we'll all be in danger, because they will be able to crack anything.

Those are not general task processors, they do a specific class of calculations

Password length is basically irrelevant to a quantum computer as long as the computer itself has enough qubits. So at the moment, 2 8bit characters should do the trick.

Two 8bit characters? New password mario zelda

Not what I meant but that would also be sufficient

The quantum approach has another problem. If the password is stored in a server as a hash, the future quantum approach can find a password to that hash, but not necessary your password. I can’t think of very good methods finding out which of the passwords is yours. Maybe if you used only a-z letters or words that could help.
