A quantum memory at telecom wavelengths

In our work we demonstrate a quantum memory natively operating in the telecommunication band. We realize our memory using a fully engineered optomechanical system and demonstrate storage times of up to 2ms.

Feedback cooling of a room temperature mechanical oscillator close to its motional groundstate

A new fishbone-like design allows us to feedback cool an optomechanical device from room temperature by 6 orders of magnitude close to its groundstate of motion.

An optomechanical Bell test

In our experiment, photons interact with mechanical oscillators through the radiation pressure force, which leads to an entangled opto-mechanical state. We use this to violate a Bell inequality, demonstrating that massive systems can be at variance with local realism.

Remote quantum entanglement between two micromechanical oscillators

Entanglement is famously known as the spooky action at a distance between two objects that can only be described with quantum theory. We have now succeeded in creating such entanglement between two massive, micromechanical resonators mediated by photons.
