Phys. Rev. B 67, 075303 (2003) [8 pages]Spectrum of qubit oscillations from generalized Bloch equationsReceived 25 February 2002; revised 27 November 2002; published 5 February 2003 We have developed a formalism suitable for calculation of the output spectrum of a detector continuously measuring quantum coherent oscillations in a solid-state qubit, starting from microscopic generalized Bloch equations. The results coincide with those obtained using Bayesian and master equation approaches. The previous results are generalized to the cases of arbitrary detector response and finite detector temperature. © 2003 The American Physical Society URL:
