Fig. 4: Temporal post-selection of quantum teleportation events.
From: Quantum teleportation with dissimilar quantum dots over a hybrid quantum network
Teleportation fidelity averaged over the \(\left\vert {\psi }^{-}\right\rangle\) and \(\left\vert {\psi }^{+}\right\rangle\) projections as a function of the BSM coincidence time window Δτ. We compare the results obtained for the fiber network case (red points) with the hybrid scenario (blue points), where teleported photons are sent over a 270 m free-space channel. On the top axis, the fraction of retained events over the total (corresponding to a coincidence time window of 400 ps) is reported as a function of Δτ.
