Qubits are hugely sensitive to their external environments, and in many cases stray particles of sunshine can introduce errors. For meaningful computation, these mistakes needs to be corrected, and mistake correction should be improved as quantum processors are scaled to greater numbers of qubits.

If quantum error correction is used to scale quantum desktops to functional programs, its overhead may undermine speedup made available from a lot of quantum algorithms.[96] In truth, for a lot of the calculations, additional sound was intentionally included, earning the answers even more unrelia
