Video Description

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.

Great video. Too brief, I think some additional explanations would do good, but it was excellent.

This is a very interesting demonstration! Like Cristi, I would have enjoyed more explanation. But it was fascinating to see a video of the entanglement relationship. Thank you and good luck!

Nice!

This was fun to watch and informative Robert, Mario, and Anton. As with other commenters, I'd have liked to see a little more content. It is kind of neat, though, that the short demonstration shows all by itself that strong correlations are taking place - which can be explained by entanglement, and are hard to explain otherwise (though not impossible). When people see it for themselves, however, the visual evidence has an impact that explanations don't.

All the Best,

Jonathan
