Faithful Quantum Teleportation via a Nanophotonic Nonlinear Bell State Analyzer

Author(s): Joshua Akin, Yunlei Zhao, Paul G. Kwiat, Elizabeth A. Goldschmidt, and Kejie Fang Quantum networking protocols, including quantum teleportation and entanglement swapping, use linear-optical Bell state measurements for heralding the distribution and transfer of quantum information. However, a linear-optical Bell state measurement requires identical photons and is susceptible to er… [Phys. Rev. Lett. 134, 160802] Published Tue Apr 22, 2025
