  • Chen, Jianxin; Chen, Xie; Duan, Runyao; Ji, Zhengfeng; Zeng, Bei (American Physical Society, 2011-05)
    The ground states of some many-body quantum systems can serve as resource states for the one-way quantum computing model, achieving the full power of quantum computation. Such resource states are found, for example, in ...
  • Sepke, Todd; Holloway, Peter; Sodini, Charles G.; Lee, Hae-Seung (Institute of Electrical and Electronics Engineers, 2009-03)
    Noise analysis for comparator-based circuits is presented. The goal is to gain insight into the different sources of noise in these circuits for design purposes. After the general analysis techniques are established, they ...
  • Yoshihara, Fumiki; Nakamura, Yasunobu; Gustavsson, Simon; Bylander, Jonas; Yan, Fei; Oliver, William D. (American Physical Society, 2011-07)
    We have measured flux-noise correlations in a tunable superconducting flux qubit. The device consists of two loops that independently control the qubit’s energy splitting and tunnel coupling. Low-frequency flux noise in ...
  • Hasinoff, Samuel William; Durand, Fredo; Freeman, William T. (Institute of Electrical and Electronics Engineers (IEEE), 2010-08)
    Taking multiple exposures is a well-established approach both for capturing high dynamic range (HDR) scenes and for noise reduction. But what is the optimal set of photos to capture? The typical approach to HDR capture ...
  • Rafiee, Morteza; Lupo, Cosmo; Mancini, Stefano (American Physical Society, 2013-09)
    We consider quantum state transfer in a fully connected spin network, in which the results indicate that it is impossible to achieve high fidelity by free dynamics. However, the addition of certain kinds of noise can be ...
  • Angeletos, George-Marios; La'O, Jennifer (University of Chicago Press, 2010)
    This paper investigates a real-business-cycle economy that features dispersed information about the underlying aggregate productivity shocks, taste shocks, and—potentially—shocks to monopoly power. We show how the ...
  • Beheshti, Soosan; Dahleh, Munther A. (Institute of Electrical and Electronics Engineers (IEEE), 2010-01)
    This paper investigates the impulse response estimation of linear time-invariant (LTI) systems when only noisy finite-length input-output data of the system is available. The competing parametric candidates are the least ...
  • Agarwal, Alekh; Negahban, Sahand; Wainwright, Martin J. (Institute of Mathematical Statistics, 2012-08)
    We analyze a class of estimators based on convex relaxation for solving high-dimensional matrix decomposition problems. The observations are noisy realizations of a linear transformation [bar through "X" symbol] of the sum ...
  • Wen, Xiao-Gang; Lu, Yuan-Ming; Wang, Zhenghan; Wang, Ziqiang (American Physical Society, 2010-03)
    In the pattern-of-zeros approach to quantum Hall states, a set of data {n;m;S[subscript a]|a=1,…,n;n,m,S[subscript a]∊N} (called the pattern of zeros) is introduced to characterize a quantum Hall wave function. In this ...
  • Todadri, Senthil; Grover, Tarun (American Physical Society, 2011-07)
    We study a time-reversal invariant non-Abelian spin-liquid state in an SU(2) symmetric spin S=1 quantum magnet on a triangular lattice. The spin liquid is obtained by quantum disordering a noncollinear nematic state. We ...
  • McGreevy, John; Swingle, Brian Gordon (American Physical Society, 2011-09)
    This paper is motivated by prospects for non-Abelian statistics of deconfined particlelike objects in 3+1 dimensions, realized as solitons with localized Majorana zero modes. To this end, we study the fermionic collective ...
  • Barkeshli, Maissam; Wen, Xiao-Gang (American Physical Society, 2010-12)
    A large class of fractional quantum Hall (FQH) states can be classified according to their pattern of zeros, which describes the order of zeros in ground-state wave functions as various clusters of electrons are brought ...
  • Schmid, Susanne; Poon, Chi-Sang (Springer-Verlag, 2012-01)
    Nonassociative learning is an implicit (non-declarative) or procedural form of learning that systematically attenuates (habituates) or augments (sensitizes) an animal’s sensory percept or behavioral response to a sensory ...
  • Lee, Chee Kong; Cao, Jianshu; Gong, Jiangbin (American Physical Society, 2012-08)
    Equilibrium canonical distribution in statistical mechanics assumes weak system-bath coupling (SBC). In real physical situations this assumption can be invalid, and equilibrium quantum statistics of the system may be ...
  • Rabbachin, Alberto; Quek, Tony Q. S.; Pinto, Pedro C.; Oppermann, Ian; Win, Moe Z. (Institute of Electrical and Electronics Engineers, 2010-11)
    There has been an emerging interest in non-coherent ultra-wide bandwidth (UWB) communications, particularly for low-data rate applications because of its low-complexity and low-power consumption. However, the presence of ...
  • Marcolli, Matilde; Trigo Neri Tabuada, Goncalo Jo; Trigo Neri Tabuada (Springer, 2013-06)
    In this article, we introduce the category of noncommutative Artin motives as well as the category of noncommutative mixed Artin motives. In the pure world, we start by proving that the classical category AM(k)[subscript ...
  • Etingof, Pavel I.; Ginzburg, Victor (European Mathematical Society, 2010)
    The hypersurface in ℂ3 with an isolated quasi-homogeneous elliptic singularity of type Ēr, r = 6, 7, 8, has a natural Poisson structure. We show that the family of del Pezzo surfaces of the corresponding type Er provides ...
  • Ran, Chongzhao; Zhao, Wei; Moir, Robert D.; Moore, Anna V. (Public Library of Science, 2001-04)
    Background: Systematic differentiation of amyloid (Aβ) species could be important for diagnosis of Alzheimer's disease (AD). In spite of significant progress, controversies remain regarding which species are the primary ...
  • Jensen, Karin B.; Kaptchuk, Ted J.; Kirsch, Irving; Raicek, Jacqueline; Lindstrom, Kara M.; Berna, Chantal; Gollub, Randy Lyanne; Ingvar, Martin; Kong, Jian (National Academy of Sciences (U.S.), 2012-09)
    The dominant theories of human placebo effects rely on a notion that consciously perceptible cues, such as verbal information or distinct stimuli in classical conditioning, provide signals that activate placebo effects. ...
  • Poh, Ming-Zher; McDuff, Daniel Jonathan; Picard, Rosalind W. (Optical Society of America, 2010-05)
    Remote measurements of the cardiac pulse can provide comfortable physiological assessment without electrodes. However, attempts so far are non-automated, susceptible to motion artifacts and typically expensive. In this ...
