Spatially-entangled Photon-pairs Generation Using Partial Spatially Coherent Pump Beam
Hugo Defienne, Sylvain Gigan
We demonstrate experimental generation of spatially-entangled photon-pairs by spontaneous parametric down conversion (SPDC) using a partial spatially coherent pump beam. By varying…
Adaptive Quantum Optics with Spatially Entangled Photon Pairs
Hugo Defienne, Matthew Reichert, Jason W. Fleischer
Light shaping facilitates the preparation and detection of optical states and underlies many applications in communications, computing, and imaging. In this Letter, we generalize l…
Optimizing the signal-to-noise ratio of biphoton distribution measurements
Matthew Reichert, Hugo Defienne, Jason W. Fleischer
Single-photon-sensitive cameras can now be used as massively parallel coincidence counters for entangled photon pairs. This enables measurement of biphoton joint probability distri…
General model of photon-pair detection with an image sensor
Hugo Defienne, Matthew Reichert, Jason W. Fleischer
We develop an analytic model that relates intensity correlation measurements performed by an image sensor to the properties of photon pairs illuminating it. Experiments using both…
