Extended Data Fig. 8: Atom-photon entanglement infidelity and relative yield under different telecom Rabi frequencies and magnetic fields after post-selecting on receiving ≥1 1389-nm photons.
From: Parallelized telecom quantum networking with an ytterbium-171 atom array
We find that using higher Rabi frequency and operating under higher B-field strength result in better atom-photon entanglement fidelities. Under a fixed B-field strength, there exist several local minima of atom-photon entanglement infidelity where the off-resonant transition from \(\left\vert \uparrow \right\rangle\) goes through multiples of 2Ï€. The star indicates the settings used our experiment.
