Quantum computers are not reliable enough to be mainstream. This is due to the high error rates in their calculations. This could change soon, as a quantum computer has shown for the first time an error-correction strategy which fixes more errors than it creates. This may be a practical way to scale up to a machine that can actually perform useful computations.
Computers store data in either a 1 or 0 format. However, errors can cause bits to flip to the wrong value.
