High-efficiency WSi superconducting nanowire single-photon detectors for quantum state engineering in the near infrared
H. Le Jeannic, V. B. Verma, A. Cavaillès +6
We report on high-efficiency superconducting nanowire single-photon detectors based on amorphous WSi and optimized at 1064 nm. At an operating temperature of 1.8 K, we demonstrated…
Quantum teleportation across a metropolitan fibre network
Raju Valivarthi, Marcel. li Grimau Puigibert, Qiang Zhou +7
If a photon interacts with a member of an entangled photon pair via a so-called Bell-state measurement (BSM), its state is teleported over principally arbitrary distances onto the…
Demonstration of EPR steering using single-photon path entanglement and displacement-based detection
T. Guerreiro, F. Monteiro, A. Martin +15
We demonstrate the violation of an EPR steering inequality developed for single photon path entanglement with displacement-based detection. We use a high-rate source of heralded si…
