We demonstrate a new biphoton manipulation and characterization technique based on electro-optic intensity modulation and time shifting. By applying fast modulation signals with a sharply peaked cross-correlation to each photon from an entangled pair, it is possible to measure temporal correlations with significantly higher precision than that attainable using standard single-photon detection. Low-duty-cycle pulses and maximal-length sequences are considered as modulation functions, reducing…

Spectrally Engineering Photonic Entanglement with a Time Lens.
A time lens based on dispersion and sum-frequency generation to spectrally engineer single photons from an entangled pair is constructed and the strong frequency anticorrelations between photons produced from spontaneous parametric down-conversion are converted to positive correlations after the time lens.
