Phys. Rev. A 61, 032102 (2000) [4 pages]Quantum-nondemolition modulation of quantum interferenceReceived 19 July 1999; revised 21 September 1999; published 9 February 2000 We propose an experiment where quantum interference between two different paths is modulated by means of a quantum nondemolition (QND) measurement on one or both the arms of an interferometer. The QND measurement is achieved in a Kerr cell. We illustrate a scheme for the realization of this experiment, and discuss some further developments. © 2000 The American Physical Society URL:
