Description

Abstract:
We will consider the simple model of an ensemble of classical random telegraph processes which allows one to study the decoherence of a quantum system in cases where the environment dynamics is slow compared to the decoherence timescale. 1/f noise is one typical such noise source as it is dominated by low frequencies. We will mostly consider the case of pure dephasing, showing in detail how one can derive the decay of the quantum state in this model. We will also discuss the conditions under which the model is realistic and where it can fail.
