the process in which a system's behaviour changes from that which can be explained by quantum mechanics to that which can be explained by classical mechanics

Generally, space charge slows down the decoherence process and can cause the loss of decoherence.

Unfortunately, random fluctuations of nearby charges introduce decoherence that limits semiconductor qubits' performance.
