摘要：

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.
