Quantum Optical Memory Device One Thousand Times Smaller Than Previous Options

Quantum Optical Memory Device One Thousand Times Smaller Than Previous Options

The prospects for optical quantum networks —in which information is transmitted by encoding data using the quantum state of photons—has been on the upswing lately, leading to some commercial quantum photonics products currently on the market. However, optical quantum memory , which is one of the key technologies for the realization of widespread, optical, quantum networks, remains a sticking point. Optical quantum memory is a device that takes a photon and encodes it with information. Unfortunately, the devices developed to date have been too large and inefficient to operate in a chip-scale quantum device. Now an international team of researchers led by a group from the California Institute of Technology (Caltech) has managed to create an optical quantum memory device that is over 1000 times smaller than anything previously available. Not only is the device significantly s...
