So in case you didn't catch that, quantum computers are supposedly going to reach into multiple realities and find the one with the correct answer and then come back to this reality with that answer. ...
It comes down to if one believes the wave is more fundamental than 1 singular block of time.
QM/QC is an approximation of behavior of time as a fluid, but it does not describe the fundamental quantized unit of time.
