Decoherence of the quantum gate in Milburn’s model of decoherence
Kyoungtae Kimm, Hwang-h. Kwon · Physical Review A · 2002
We study the decoherence properties of a two-qubit quantum swap gate in Milburn's model of decoherence where the gate is realized by the quantum-dot system. We examine how the so-called intrinsic decoherence may degrade the gate purity and gate fidelity of the quantum swap gate and also present a potential source for the occurrence of Milburn's equation in the system of concern.
