Considered one of the greatest difficulties associated with setting up quantum personal computers is controlling or eliminating quantum decoherence. This usually indicates isolating the process from its surroundings as interactions Together with the exterior entire world lead to the program to decohere. Having said that, other resources of decohere

If quantum mistake correction is accustomed to scale quantum computer systems to useful apps, its overhead may possibly undermine speedup provided by many quantum algorithms.[ninety six]Specifically, nearly all of the favored public crucial ciphers are determined by The issue of factoring integers or the discrete logarithm trouble, both of those of
