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

Rancic, Milos; Hedges, Morgan P; Ahlefeldt, Rose; Sellars, Matthew


Quantum memories for light will be essential elements in future long-range quantum communication networks. These memories operate by reversibly mapping the quantum state of light onto the quantum transitions of a material system. For networks, the quantum coherence times of these transitions must be long compared to the network transmission times, approximately 100 ms for a global communication network. Due to a lack of a suitable storage material, a quantum memory that operates in the 1,550nm...[Show more]
