Entanglement of Two Remote Mechanical Resonators

ORAL

Abstract

Entanglement is a key feature of quantum mechanics and plays an important role in many quantum information processing protocols. Here we report on the entanglement of two massive mechanical oscillators located on separate chips. Intriguingly, the silicon photonics devices employed in this experiment can serve as long-lived quantum memories and are directly interfaced to photons in the telecom wavelength range around 1550nm. We further report on the observation of entanglement between a flying telecom photon and a pair of such quantum memories.
