  • Zhuang, Quntao; Zhang, Zheshen; Shapiro, Jeffrey H (American Physical Society, 2017-10)
    Lidar is a well-known optical technology for measuring a target's range and radial velocity. We describe two lidar systems that use entanglement between transmitted signals and retained idlers to obtain significant quantum ...
  • Zhang, Zheshen; Wong, Franco N. C.; Shapiro, Jeffrey H.; Mouradian, Sara L.; Wong, Franco N. C. (American Physical Society, 2015-03)
    Nonclassical states are essential for optics-based quantum information processing, but their fragility limits their utility for practical scenarios in which loss and noise inevitably degrade, if not destroy, nonclassicality. ...
  • Swingle, Brian Gordon (American Physical Society, 2010-07)
    Free fermions with a finite Fermi surface are known to exhibit an anomalously large entanglement entropy. The leading contribution to the entanglement entropy of a region of linear size L in d spatial dimensions is ...
  • He, Huan; Tiwari, Apoorv; Zheng, Yunqin; Ye, Peng; Wen, Xueda (American Physical Society, 2018-02)
    Excitations in (3+1)-dimensional [(3+1)D] topologically ordered phases have very rich structures. (3+1)D topological phases support both pointlike and stringlike excitations, and in particular the loop (closed string) ...
  • Maghrebi, Mohammad F.; Reid, M. T. Homer (American Physical Society, 2015-04)
    A dispersive medium becomes entangled with zero-point fluctuations in the vacuum. We consider an arbitrary array of material bodies weakly interacting with a quantum field and compute the quantum mutual information between ...
  • Pretko, Michael; Senthil, Todadri (American Physical Society, 2016-09)
    We here investigate the entanglement structure of the ground state of a (3+1)-dimensional U(1) quantum spin liquid, which is described by the deconfined phase of a compact U(1) gauge theory. A gapless photon is the only ...
  • Cotler, Jordan S.; Hertzberg, Mark P.; Mezei, Márk; Mueller, Mark (Springer Berlin Heidelberg, 2016-11)
    We compute the entanglement and Rényi entropy growth after a global quench in various dimensions in free scalar field theory. We study two types of quenches: a boundary state quench and a global mass quench. Both of these ...
  • Liu, Hong; Suh, Sunok Josephine (American Physical Society, 2014-03)
    We derive in detail several universal features in the time evolution of entanglement entropy and other nonlocal observables in quenched holographic systems. The quenches are such that a spatially uniform density of energy ...
  • Corkeron, Peter; Moore, Michael; van der Hoop, Julie (Wiley Blackwell, 2017-01)
    Individuals store energy to balance deficits in natural cycles; however, unnatural events can also lead to unbalanced energy budgets. Entanglement in fishing gear is one example of an unnatural but relatively common ...
  • Swingle, Brian Gordon (American Physical Society, 2012-09)
    We show how recent progress in real space renormalization group methods can be used to define a generalized notion of holography inspired by holographic dualities in quantum gravity. The generalization is based upon ...
  • Zhang, Zheshen; Tengner, Maria; Zhong, Tian; Wong, Franco N. C.; Shapiro, Jeffrey H. (American Physical Society, 2013-07)
    Entanglement is essential to many quantum information applications, but it is easily destroyed by quantum decoherence arising from interaction with the environment. We report the first experimental demonstration of an ...
  • Scott, Susan V.; Orlikowski, Wanda J. (Management Information Systems Research Center, Carlson School of Management, University of Minnesota, 2014)
    Information systems researchers have shown an increasing interest in the notion of sociomateriality. In this paper, we continue this exploration by focusing specifically on entanglement: the inseparability of meaning and ...
  • Vijay, Sagar; Fu, Liang (American Physical Society, 2015-06)
    We study the entanglement spectrum of a translationally invariant lattice system under a random partition, implemented by choosing each site to be in one subsystem with probability p ∈ [0,1]. We apply this random partitioning ...
  • Lee, Tony E.; Chan, Ching-Kit; Wang, Shenshen (American Physical Society, 2014-02)
    We study the synchronization of dissipatively coupled van der Pol oscillators in the quantum limit, when each oscillator is near its quantum ground state. Two quantum oscillators with different frequencies exhibit an ...
  • Liu, Hong; Suh, Sunok Josephine (American Physical Society, 2014-01)
    We consider the time evolution of entanglement entropy after a global quench in a strongly coupled holographic system, whose subsequent equilibration is described in the gravity dual by the gravitational collapse of a thin ...
  • Raczynski, Arkadiusz R.; Muthupalani, Sureshkumar; Schlieper, Katherine Ann; Fox, James G.; Tannenbaum, Steven Robert; Schauer, David B. (Public Library of Science, 2012-03)
    Acute and chronic forms of inflammation are known to affect liver responses and susceptibility to disease and injury. Furthermore, intestinal microbiota has been shown critical in mediating inflammatory host responses in ...
  • Walker, Graham C.; Arnold, Markus F. F.; Caro-Hernandez, Paola; Tan, Karen; Runti, Giulia; Wehmeier, Silvia; Scocchi, Marco; Doerrler, William T.; Ferguson, Gail P. (American Society for Microbiology, 2013-11)
    yaiW is a previously uncharacterized gene found in enteric bacteria that is of particular interest because it is located adjacent to the sbmA gene, whose bacA ortholog is required for Sinorhizobium meliloti symbiosis and ...
  • Zheng, Tengfei; Nolan, Elizabeth M. (American Chemical Society (ACS), 2014-06)
    The design, synthesis, and characterization of enterobactin–antibiotic conjugates, hereafter Ent-Amp/Amx, where the β-lactam antibiotics ampicillin (Amp) and amoxicillin (Amx) are linked to a monofunctionalized enterobactin ...
  • Thomson, John M.; Hansen, Richard; Berry, Susan H.; Hope, Mairi E.; Murray, Graeme I.; Mukhopadhya, Indrani; McLean, Mairi H.; Shen, Zeli; Fox, James G.; El-Omar, Emad; Hold, Georgina L. (Public Library of Science, 2011-02)
    Background Changes in bacterial populations termed “dysbiosis” are thought central to ulcerative colitis (UC) pathogenesis. In particular, the possibility that novel Helicobacter organisms play a role in human UC has ...
  • Muzhikyan, Aramazd; Farid, Amro M.; Youcef-Toumi, Kamal (Institute of Electrical and Electronics Engineers (IEEE), 2015-03)
    In recent years, renewable energy has developed to address energy security and climate change drivers. However, as energy resources, they possess a variable and uncertain nature that significantly complicates grid balancing ...
