Quantum interference between two single photons emitted by independently trapped atoms

Nature 440, 779-782 (6 April 2006) http://dx.doi.org/10.1038/nature04628

Are simultaneous Bell measurements possible?

New Journal of Physics 8, 39 (2006) http://dx.doi.org/10.1088/1367-2630/8/3/039

The author argued that it is not possible to construct simultaneous measurements for more than two entangled particles based on the so-called uniqueness property.
