Photon Quantum Entanglement and Vacuum Fluctuations by Spontaneous Param

The
video of an experiment showing vacuum fluctuations amplified by
spontaneous parametric down-conversion (SPDC). Using a UV laser and a
BBO crystal. The UV laser is used as the pump, and it is visible on the
left. The red ring is generated by SPDC. Small fluctuations in the blue
spot are due to camera noise, whereas much more pronounced fluctuations
in the red ring (especially visible in the dimer part of the ring) are
amplified vacuum fluctuations, as predicted by the theory of SPDC.
