    Shah, Shahnawaz; Lin, Xiao; Shen, Lian; Renuka, Maturi; Zhang, Baile; Chen, Hongsheng (2018)
    The ability to control the polarization of light at the extreme nanoscale has long been a major scientific and technological goal for photonics. Here we predict the phenomenon of polarization splitting through van der Waals ...

    Hovsepyan, G. H.; Shahinyan, A. R.; Chew, Lock Yue; Kryuchkyan, G. Yu. (2016)
    We discuss phase-locking phenomenon at low-level of quanta and quantum statistics for parametrically driven nonlinear Kerr resonator (PDNR). Oscillatory mode of PDNR is created in the process of a degenerate down-conversion ...
  • Time-consistent mean-variance portfolio selection with only risky assets 

    Pun, Chi Seng (2018)

    Yang, Junfeng; Shen, Yixiao; Lim, Yang Jie; Yoshikai, Naohiko (2018)
    Cobalt–diphosphine catalysts promote ring-opening coupling reactions between cyclopropanols and unactivated internal alkynes, affording either β-alkenyl ketones or multisubstituted cyclopentenol derivatives in good yields ...
  • On low-risk heavy hitters and sparse recovery schemes 

    Li, Yi; Nakos, Vasileios; Woodruff, David P. (2018)
    We study the heavy hitters and related sparse recovery problems in the low failure probability regime. This regime is not well-understood, and the main previous work on this is by Gilbert et al. (ICALP'13). We recognize ...
  • Lossless dimension expanders via linearized polynomials and subspace designs 

    Guruswami, Venkatesan; Resch, Nicolas; Xing, Chaoping (2018)
    For a vector space F^n over a field F, an (eta,beta)-dimension expander of degree d is a collection of d linear maps Gamma_j : F^n -> F^n such that for every subspace U of F^n of dimension at most eta n, the image of U ...
  • Linear sketching over F2 

    Kannan, Sampath; Mossel, Elchanan; Sanyal, Swagato; Yaroslavtsev, Grigory (2018)
    We initiate a systematic study of linear sketching over F_2. For a given Boolean function treated as f : F_2^n -> F_2 a randomized F_2-sketch is a distribution M over d x n matrices with elements over F_2 such that Mx ...
  • The complexity of quantum disjointness 

    Klauck, Hartmut (2017)
    We introduce the communication problem QNDISJ, short for Quantum (Unique) Non-Disjointness, and study its complexity under different modes of communication complexity. The main motivation for the problem is that it is a ...
  • How long can optimal locally repairable codes be? 

    Guruswami, Venkatesan; Xing, Chaoping; Yuan, Chen (2018)
    A locally repairable code (LRC) with locality r allows for the recovery of any erased codeword symbol using only r other codeword symbols. A Singleton-type bound dictates the best possible trade-off between the dimension ...
  • Fidelity of quantum strategies with applications to cryptography 

    Gutoski, Gus; Rosmanis, Ansis; Sikora, Jamie (2018)
    We introduce a definition of the fidelity function for multi-round quantum strategies, which we call the strategy fidelity, that is a generalization of the fidelity function for quantum states. We provide many interesting ...

    Anshu, Anurag; Gavinsky, Dmitry; Jain, Rahul; Kundu, Srijita; Lee, Troy; Mukhopadhyay, Priyanka; Santha, Miklos; Sanyal, Swagato (2018)
    Let the randomized query complexity of a relation for error probability epsilon be denoted by R_epsilon(). We prove that for any relation f contained in {0,1}^n times R and Boolean function g:{0,1}^m -> {0,1}, R_{1/3}(f o ...

  • Quantum recommendation systems 

    Kerenidis, Iordanis; Prakash, Anupam (2017)
    A recommendation system uses the past purchases or ratings of n products by a group of m users, in order to provide personalized recommendations to individual users. The information is modeled as an m \times n preference ...
  • Deterministic heavy hitters with sublinear query time 

    Li, Yi; Nakos, Vasileios (2018)
