Entangled diamonds

Here is a neat result from some local researchers: quantum entangled diamonds http://www.sciencemag.org/content/334/6060/1213.summary http://www.sciencemag.org/content/334/6060/1253.abstract They got two millimetre-sized diamonds entangled with each other over a distance of several centimetres. The trick was to use the phonon modes, the internal vibrations in the diamond lattice - they are quantum mechanical yet rather resilient to the outside world. So a laser photon is split into a superposition, one half is used to stimulate a phonon in one diamond and the other entangles a phonon in the other. Voila! Entangled diamonds at room temperature. Good news for quantum computing.
