Quantum teleportation over 100 km of fiber using MoSi superconducting nanowire single-photon detectors

Using high-efficiency superconducting nanowire single-photon detectors based on MoSi, we successfully achieved quantum teleportation of weak coherent states over 100 km of fiber with an average fidelity of 82.9 ± 1.7% for six distinct input states.
