# Nonlocal modulation of entangled photons

@article{Harris2008NonlocalMO, title={Nonlocal modulation of entangled photons}, author={S. E. Harris}, journal={Physical Review A}, year={2008}, volume={78}, pages={021807} }

We consider ramifications of the use of high-speed light modulators to questions of correlation and measurement of time-energy entangled photons. Using phase modulators, we find that temporal modulation of one photon of an entangled pair, as measured by correlation in the frequency domain, may be negated or enhanced by modulation of the second photon. Using amplitude modulators, we describe a Fourier technique for measurement of biphoton wave functions with slow detectors.
