Effective dephasing for a qubit interacting with a transverse classical field / C. Benedetti, M.G.A. Paris. - In: INTERNATIONAL JOURNAL OF QUANTUM INFORMATION. - ISSN 0219-7499. - 12:2(2014 Apr), pp. 1461004.1-1461004.9.
Abstract:
We address the dynamics of a qubit interacting with a quasi static random classical field having both a longitudinal and a transverse component and described by a Gaussian stochastic process. In particular, we analyze in detail the conditions under which the dynamics may be effectively approximated by a unitary operation or a pure dephasing without relaxation.
