Coherent Spin Control at the Quantum Level in an Ensemble-Based Optical Memory
Coherent Spin Control at the Quantum Level in an Ensemble-Based Optical Memory
Long-lived quantum memories are essential components of a long-standing goal of remote distribution of entanglement in quantum networks. These can be realized by storing the quantum states of light as single-spin excitations in atomic ensembles. However, spin states are often subjected to different dephasing processes that limit the storage time, …
