Nanophotonic rare-earth quantum memory with optically controlled retrieval
“Researchers have built a quantum memory device that is a millionth times smaller than previsous devices. It is small enough to install on a chip.
This crystal is the first quantum memory device of its kind that could fit on a chip alongside nano-sized instruments for detecting and sending signals written in quantum bits.The device iis only about 10 micrometers long and 0.7 micrometers wide — about as wide as a bacterial cell…”
