Cooling matter from a distance

Researchers have succeeded in forming a control loop consisting of two quantum systems separated by a distance of one meter. Within this loop, one quantum system -- a vibrating membrane -- is cooled by the other -- a cloud of atoms, and the two systems are coupled to one another by laser light. Interfaces such as this allow different kinds of quantum systems to interact with one another even over relatively large distances and will play a key role in quantum technologies of the future.
