  1. 604. Wigner function negativity and contextuality in quantum computation on rebits
    Robert Raussendorf (UBC)

    Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)
    Invited Speaker / Conférencier invité
    We describe a universal scheme of quantum computation by state injection on rebits (states with real density matrices). For this scheme, we establish contextuality and Wigner function negativity as computational resources, extending results of [M. Howard et al., Nature 510, 351–355 (2014)] to two-level systems. For this purpose, we define a Wigner function suited to systems of n rebits, and...

  2. 500. Orbital Interference Effects in Nanowire Josephson Junctions for Exploring Majorana Physics
    Jonathan Baugh (University of Waterloo)

    Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)
    Invited Speaker / Conférencier invité
    The Josephson effect in a nanowire-based superconductor-normal-superconductor (SNS) junction is studied theoretically and experimentally, focusing on the effects of nanoscale confinement on the current-phase relationship of the junction. We identify a new type of Josephson interference based on the coupling of an applied axial magnetic flux to N-section Andreev quasiparticles (bound and...

  3. 819. Multiqubit entangled channels for quantum communication in networks
    Shohini Ghose (Wilfrid Laurier University)

    Theoretical Physics / Physique théorique (DTP-DPT)
    Invited Speaker / Conférencier invité
    Multiqubit entangled states are an important resource for networked information processing and communication. Here, we explore the use of entangled channels for various controlled teleportation schemes. In controlled teleportation (CT), the teleportation can proceed only with the permission and participation of one or more controllers. Thus, the controller’s role is of key importance in CT...
