If quantum error correction is utilized to scale quantum pcs to functional programs, its overhead may undermine speedup made available from a lot of quantum algorithms.[96]Scalability: Another key challenge is scalability. Creating a significant-scale quantum Laptop with a large number of qubits is incredibly complicated, since it necessitates the

Amongst the best problems involved with developing quantum personal computers is controlling or eradicating quantum decoherence. This commonly signifies isolating the program from its atmosphere as interactions with the exterior globe induce the process to decohere. Nonetheless, other sources of decoherence also exist. Examples include things like
