Smallest-yet optical quantum memory device is a storage medium for optical quantum networks with the potential to be scaled up for commercial use. For the first time, an international team led by engineers at Caltech has developed a computer chip with nanoscale optical quantum memory. Quantum memory stores information on individual quantum particles – in this case, photons of light.

This allows it to take advantage of the peculiar features of quantum mechanics (such as superposition, in which a quantum element can exist in two distinct states simultaneously) to store data more efficiently and securely...
