High-performance cavity-enhanced quantum memory with warm atomic cell
Quantum memories usually suffer from a trade-off between efficiency and excess noise. Here, by exploiting the time-reversal approach for improving modes matching, the authors show a warm-atomic-cell-based cavity-enhanced memory with 67% efficiency and noise level close to quantum noise limit.
