IBM claims to operate a 65 qubit quantum computer.
How long would it take to crack a scrypt cipher with this quantum computer right now?
How about the 1000 qubit quantum computer promised by IBM in 2023?

I am not an expert on quantum computing, but considering that scrypt uses millions of bits of state, I don't expect that quantum computers would be very useful any time soon.
