Einstein's box

Einstein's box

[
thumb|right|200px|_Einstein's thought experiment of 1930 as designed by Bohr. Einstein's box was supposed to prove the violation of the indeterminacy relation between time and energy.]

Einstein's box is a theoretical chamber in a thought experiment, from which trapped light is released one photon at a time.

A group of French physicists claim to have built such a box, 1.1 inches big, which allows them to capture a photon for a seventh of a second.
