A team of researchers from the U.K., Germany and Russia has used the unpredictable nature of quantum mechanics to create a device capable of generating truly random numbers. In their paper published in the journal Physical ...
A team of researchers with members from China, Germany, the U.K. and the U.S. has found a way to entangle photons generated millions of miles apart. In their paper published in the journal Physical Review Letters, the researchers ...
If you want to get the greatest benefit from a beam of light—whether to detect a distant planet or remedy an aberration in the human eye—you need to be able to measure its beam front information.
