Decoherence of a qubit by non-Gaussian noise at an arbitrary working point
arXiv:cond-mat/0603575 · doi:10.1103/PhysRevB.74.024509
Abstract
The decoherence of a qubit due to a classical non-Gaussian noise with correlation time longer than the decoherence time is discussed for arbitrary working points of the qubit. A method is developed that allows an exact formula for the phase memory functional in the presence of independent random telegraph noise sources to be derived.
