    Coherent cavity networks with complete connectivity

    Full text link
    When cavity photons couple to an optical fiber with a continuum of modes, they usually leak out within a finite amount of time. However, if the fiber is about one meter long and linked to a mirror, photons bounce back and forth within the fiber on a much faster time scale. As a result, {\em dynamical decoupling} prevents the cavity photons from entering the fiber. In this paper we use the simultaneous dynamical decoupling of a large number of distant cavities from the fiber modes of linear optics networks to mediate effective cavity-cavity interactions in a huge variety of configurations. Coherent cavity networks with complete connectivity can be created with potential applications in quantum computing and simulation of the complex interaction Hamiltonians of biological systems.Comment: revised version, improved analysis, 4 pages and 4 figure

    Tuning the Tadpole Improved Clover Wilson Action on Coarse Anisotropic Lattices

    Get PDF
    Wilson quark action, with tadpole improved clover term added, is studied on coarse anisotropic lattices. The bare velocity of light parameter in this action is determined non-perturbatively using the pseudo-scalar and vector meson dispersion relations for various values of the gauge coupling β\beta and bare quark mass parameter κ\kappa.Comment: 7 pages LateX, typeset with elsart.cls, 1 figure, 5 tables (4 more tables added), 2 references adde
