a Theoretical teleportation fidelity as a function of the quantum resources available for the protocol, computed for the case of a 50% BSM. The white curve highlights the maximum achievable fidelity with classical resources, i.e., for a protocol only relying on classical correlations. The white star points out the expected teleportation fidelity as estimated with our theoretical model. In particular, our Bell state fidelity is 0.94 ± 0.01 and the HOM visibility for 30 ps coincidence window is VHOM = 0.57 ± 0.02, yielding an average teleportation fidelity FT = 0.827 ± 0.006. b Experimental process matrices \({\chi }_{{\psi }^{+/-}}\) for the teleportation protocol, as defined in ref. 62, reported both for the projection on \(\left\vert {\psi }^{-}\right\rangle\) (top) and \(\left\vert {\psi }^{+}\right\rangle\) (bottom), and in comparison with the corresponding ideal process matrix (dashed). The matrices are represented in terms of the quantum operations I (the identity), X = σX, Y = −iσY and Z = σZ, where {σX/Y/Z} are the Pauli matrices.
