Phys. Rev. A 80, 033840 (2009) [13 pages]Optimal waveform estimation for classical and quantum systems via time-symmetric smoothingSee Also: Publisher's Note Received 29 June 2009; published 28 September 2009; publisher error corrected 30 September 2009 Classical and quantum theories of time-symmetric smoothing, which can be used to optimally estimate wave forms in classical and quantum systems, are derived using a discrete-time approach, and the similarities between the two theories are emphasized. Application of the quantum theory to homodyne phase-locked loop design for phase estimation with narrowband squeezed optical beams is studied. The relation between the proposed theory and weak value theory of Aharonov et al. is also explored. © 2009 The American Physical Society URL:
