Comment on "Continuous quantum measurement: inelastic tunneling and lack   of current oscillations"
  This is a comment on recent paper by T.M. Stace and S.D. Barrett, PRL 92, 136802 (2004). We show that the main result of the paper, absence of the spectral peak for continuous weak measurement of coherent oscillations in a qubit, is incorrect.
