  • Photonic quantum memory with polarization-to-time entanglement conversion and time-to-polarization entanglement conversion
    Patent number: 10222822
    Abstract: A photonic quantum memory is provided. The photonic quantum memory includes entanglement basis conversion module configured to receive a first polarization-entangled photon pair and to produce a second entangled photon pair. The second polarization-entangled photon pair can be a time-bin entangled or a propagation direction-entangled photon pair. The photonic quantum memory further includes a photonic storage configured to receive the second entangled photon pair from the basis conversion module and to store the second entangled photon pair.
    Type: Grant
    Filed: December 22, 2017
    Date of Patent: March 5, 2019
    Assignee: The MITRE Corporation
    Inventors: Gerald N. Gilbert, Jonathan S. Hodges, Stephen Peter Pappas, Yaakov Shmuel Weinstein

  • Method and apparatus for quantum mechanical entanglement protection
    Patent number: 9720437
    Abstract: Embodiments of the present invention provide systems and methods to robustly inter-convert between polarization-entangled photon pairs and time-entangled photon pairs, such that produced polarization-entangled photons pairs can be converted into time-entangled photon pairs, stored as time-entangled photon pairs to preserve the entanglement for longer periods of time, and then converted back to polarization-entangled photon pairs when ready for manipulation, processing, and measurement by a quantum application.
