Entanglement is usually fragile in room-temperature solids, owing to strong interactions both internally and with the noisy environment. We generated motional entanglement between vibrational states of two spatially separated, millimeter-sized diamonds at room temperature. By measuring strong nonclassical correlations between Raman-scattered photons, we showed that the quantum state of the diamonds has positive concurrence with 98% probability. Our results show that entanglement can persist in the classical context of moving macroscopic solids in ambient conditions.

In their experiment the German team, led by Markus Oberthaler at the Kirchhoff Institute for Physics, have created a special form of quantum entanglement, called mode entanglement, which rather than involving two particles involves two gases, each containing on average 40 particles. In each gas they measured a property called quadrature and found that the values of quadrature in the gases correlate to a greater extent than classical (that is non-quantum) physics can explain. What is novel about their work is the method they used for accessing these quadratures. "It took so long to get access to [the quadratures] since they are 'encoded' in noise — which is tricky to observe since there are usually many annoying noise sources which are just classical," says Oberthaler. "Thus the experimental challenge is to get the environment under control such that technical noise is not hiding the interesting 'quantum noise'." The result has been published in Nature.

How could "squeezed light" and the phenomenon of entanglement help in the search for ripples in spacetime?
