Abstract

We demonstrate a proof-of-principle experimental realization of a novel technique that uses fast amplitude modulators to measure biphoton waveforms whose temporal lengths are shorter than the resolution time of present single photon counting modules.

We generate photons with sub-natural linewidths and temporal lengths that are sufficiently long that they may be easily modulated. Results include a new technique for measuring the temporal shape of biphotons. Article not Available.

We propose and demonstrate a new method for temporal characterization of entangled photons based on electro-optic modulation and time shifting. Our technique reduces the resolution limits induced by the large timing jitters in single-photon detectors.

We describe a proof-of-principal experiment demonstrating a Fourier technique for measuring the shape of biphoton wavepackets that vary rapidly as compared to the speed of available photon detectors. The technique uses synchronously driven telecommunication modulators.

We use EIT to generate biphotons with a temporal width of about 400 ns. A detected Stokes photon sets the time origin for electro-optic modulation (amplitude or phase) of an anti-Stokes photon.

Nonlocal Modulation of Biphotons

Steven Sensarn, G. Y. Yin, Stephen E. Harris

We experimentally describe a new quantum effect where temporal modulation of one photon of an entangled pair, as measured by frequency-domain correlation, may be negated or enhanced by modulation of the second photon.
