Long-lived and multiplexed atom-photon entanglement interface with feed-forward-controlled readouts

Long-lived and multiplexed atom-photon entanglement interface with feed-forward-controlled readouts

The quantum interface to generate entanglement between a flying photonic qubit and a stationary qubit is a key functionality for the quantum internet. The authors demonstrate a multiplexed quantum interface that stores three long-lived spin-wave qubits. A significant improvement in the rate of gener...

description The quantum interface to generate entanglement between a flying photonic qubit and a stationary qubit is a key functionality for the quantum internet. The authors demonstrate a multiplexed quantum interface that stores three long-lived spin-wave qubits. A significant improvement in the rate of generating spin-photon entanglement has been achieved, opening a promising route toward large-scale, long-haul quantum networks.
