Cavity-free photon blockade induced by many-body bound states.
Zheng, Huaixiu; Gauthier, Daniel J; Baranger, Harold U (Physical review letters, 2011-11)The manipulation of individual, mobile quanta is a key goal of quantum communication; to achieve this, nonlinear phenomena in open systems can play a critical role. We show theoretically that a variety of strong quantum ... -
Decoy-state quantum key distribution with nonclassical light generated in a one-dimensional waveguide.
Zheng, Huaixiu; Gauthier, Daniel J; Baranger, Harold U (Optics letters, 2013-03)We investigate a decoy-state quantum key distribution (QKD) scheme with a sub-Poissonian single-photon source, which is generated on demand by scattering a coherent state off a two-level system in a one-dimensional waveguide. ... -
Interacting Photons in Waveguide-QED and Applications in Quantum Information Processing
Zheng, Huaixiu (2013)Strong coupling between light and matter has been demonstrated both in classicalcavity quantum electrodynamics (QED) systems and in more recent circuit-QEDexperiments. This enables the generation of strong nonlinear photon-photon ... -
Persistent quantum beats and long-distance entanglement from waveguide-mediated interactions.
Zheng, Huaixiu; Baranger, Harold U (Physical review letters, 2013-03)We study photon-photon correlations and entanglement generation in a one-dimensional waveguide coupled to two qubits with an arbitrary spatial separation. To treat the combination of nonlinear elements and 1D continuum, ... -
Quantum phase transition in a resonant level coupled to interacting leads.
Mebrahtu, Henok T; Borzenets, Ivan V; Liu, Dong E; Zheng, Huaixiu; Bomze, Yuriy V; Smirnov, Alex I; Baranger, Harold U; ... (8 authors) (Nature, 2012-08)A Luttinger liquid is an interacting one-dimensional electronic system, quite distinct from the 'conventional' Fermi liquids formed by interacting electrons in two and three dimensions. Some of the most striking properties ... -
Waveguide-QED-based photonic quantum computation.
Zheng, Huaixiu; Gauthier, Daniel J; Baranger, Harold U (Physical review letters, 2013-08)We propose a new scheme for quantum computation using flying qubits--propagating photons in a one-dimensional waveguide interacting with matter qubits. Photon-photon interactions are mediated by the coupling to a four-level ...
