Phys. Rev. A 59, 1654–1657 (1999)Propagation of transient quantum coherenceReceived 23 January 1998; revised 18 August 1998; published in the issue dated February 1999 We perform a time-resolved quantum interference experiment based on the effect of induced coherence without induced emission using two pulsed parametric down-conversion sources. We periodically vary the transmission of the first source’s idler beam and measure the time-dependent visibility of fringes in the interference between the two signal beams. The visibility is found to be correlated with the transmissivity with a time delay corresponding to a combined path of the first idler and the second signal beam. The experiment is discussed in the context of the delayed choice experiments. © 1999 The American Physical Society URL:
