Real-Time Imaging of Quantum Entanglement

Quantum entanglement – which Einstein called "spooky action at a distance" – is one of most prominent and mind boggling features of quantum mechanics. To image the effects of entanglement directly, we created in our experiment a pair of entangled photons. The video shows images of single photon patterns, recorded with a triggered intensified CCD camera, where the influence of a measurement of one photon on its entangled partner photon is imaged in real-time. In our experiment, the immediate change of the monitored mode pattern is a result of the polarization measurement on the distant partner photon.
