Fast Photon-Mediated Entanglement of Continuously Cooled Trapped Ions for Quantum Networking
Fast Photon-Mediated Entanglement of Continuously Cooled Trapped Ions for Quantum Networking
We entangle two cotrapped atomic barium ion qubits by collecting single visible photons from each ion through in vacuo 0.8 NA objectives, interfering them through an integrated fiber beam splitter and detecting them in coincidence. This projects the qubits into an entangled Bell state with an observed fidelity lower bound …
