  1. 1090. Testing Landauer’s Principle in a Feedback Trap
    John Bechhoefer (Simon Fraser University)

    Invited Speaker / Conférencier invité
    Landauer’s principle, formulated in 1961, postulates that irreversible logical or computational operations such as memory erasure require work, no matter how slowly they are performed. For example, to “reset to one” a one-bit memory requires at least kT ln2 of work, which is dissipated as heat. Bennett and, independently, Penrose later pointed out a link to Maxwell’s demon: Were Landauer’s...

  2. 1363. A photonic link for donor spin qubits in silicon
    Prof. Stephanie Simmons (SFU)

    Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)
    Invited Speaker / Conférencier invité
    The electronic and nuclear spins of shallow donor impurities in silicon have many highly attractive properties as qubits for a semiconductor-based quantum information technology. In addition to being compatible with standard CMOS processing, these qubits are atomically identical, have demonstrated incredibly long relaxation times, T1, and coherence times, T2, and a single-spin technology has...

  3. 1260. Repeated Interaction with Ensemble of Ancillas
    Mr Daniel Grimmer (University of Waterloo)
    16/06/2016, 14:15
    Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)
    Oral (Student, Not in Competition) / Orale (Étudiant(e), pas dans la compétition)
    We investigate the general open dynamics of a quantum system S undergoing a bombardment of short (unitary) interactions with an environment made of individual ancillas. We show how decoherence emerges from the fully unitary interaction of S with a large set of (in general non-identical) ancillas, and we compute the master equation that governs the dynamics of the system. Our findings may have...

  4. 1314. Shape dependence of two-cylinder Renyi entropies for a free boson lattice field theory
    Denis Dalidovich (Perimeter Institute for Theoretical Physics)
    16/06/2016, 14:30
    Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)
    Oral (Non-Student) / orale (non-étudiant)
    We study the bipartite von Neumann and $\alpha =2$ Renyi entanglement entropies for a system of free bosons put on a torus cut into two cylinders. The torus is formed out of the $L\times L$ square lattice, and the entropy is supposed to scale as $S = a L + c \gamma (L_A/L) + \cdots$, with $L_A$ being the size of the partitioned region. $c$ and $a$ are some constants and the function...
