An international team of researchers (Switzerland, USA- MIT) entangled the photon and the phonon produced in the fission of an incoming laser photon inside the crystal by designing an experiment in which the photon-phonon pair could be created at two different instants. Classically, it would result in a situation where the pair is created at time t1 with 50% probability, or later t2 with 50% probability. They measured the decay of these hybrid photon-phonon Bell correlations with sub-picosecond time resolution and found that they survive over several hundred oscillations at ambient conditions. Their method offers a universal approach to generate entanglement between light and molecular vibrations. Moreover, the results pave the way for the study of quantum correlations in more complex solid-state and molecular systems in their natural state…read more. Open Access TECHNICAL ARTICLE
