DOI: 10.1021/acsphotonics.7b00514
Abstract: Quantum nonlocality, i.e., the presence of strong correlations in spatially separated systems that are forbidden by local realism, lies at the heart of quantum communications and quantum computing. Here, we use polarization-entangled photon pairs to… read more here.

DOI: 10.1103/physreva.100.023850
Abstract: An entangled photon experiment has been performed with a large variation of the temperature of the non-linear crystal generating the entangled pair by spontaneous downconversion. The photon pairs are separated by a nonpolarizing beamsplitter, and… read more here.

DOI: 10.1103/physrevb.98.104509
Abstract: It was theoretically proposed that a forward-biased p-n junction with a superconducting layer (P-N-S), would produce pure, polarization entangled photons due to inherent spin-singlet pairing of electrons. However, any heterostructure interface generically induces Rashba spin-orbit… read more here.

DOI: 10.1364/oe.475465
Abstract: Quantum measurements that use the entangled photons' polarization to encode quantum information require calibration and alignment of the measurement bases between spatially separate observers. Because of the changing birefringence in optical fibers arising from temperature… read more here.
