Optically addressable nuclear spins in a solid with a six-hour coherence time

An essential ingredient of future worldwide quantum communication is the generation of long-lived entangled quantum states; a coherence time of six hours is now reported for optically addressable nuclear spins in europium-doped yttrium orthosilicate.

Coherence time of over a second in a telecom-compatible quantum memory storage material

A candidate for efficient broadband quantum memory at telecommunication wavelengths is identified. The long coherence time and the efficient optical spin pumping demonstrated in the experiment make it practical for spin-wave storage.
