Towards Satellite-Suited Noise-Free Quantum Memories
Quantum memories on satellites will allow to circumvent transmission losses in long-distance quantum communication. We demonstrate a warm Caesium vapour memory based on EIT with an unconditional noise floor of 1.2 • 10-3 due to collision-induced fluorescence.
