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.

I watched, commented and rated earlier your video. If you have time, I would appreciate if you will watch and rate my videos

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!
Cheers

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

I am hoping you will have time to rate and comment on my video..
Can the Mandelbrot Set help us understand the Cosmos?I spoke with you briefly at FFP11 in Paris, Prof. Zeilinger, and as then I wish you continued success in your research.

Jonathan
