Quantum memories
Quantum memories are devices that take a quantum state carried by light, hold it, and release it later. A solid-state memory has reached efficiency of up to 69%, and nuclear spin coherence has been measured for hours, but the best results come from separate experiments, and none of the sources reviewed shows a memory that combines long storage, high efficiency and high fidelity in one device.
