Error correction and control are vital for any system to be reliable.

Thankfully the ability to run simultaneously and vet against multiple outputs should overcome this fault for a time.

This doesn't work because the success probability drops exponentially in the length of the algorithm. It is possible that any real application requires quantum error correction which has not been demonstrated in any meaningful way.
