  • Detecting quantum entanglement : entanglement witnesses and uncertainty relations 
    Gühne, Otfried (Hannover : Universität, 2004)
    [no abstract]
  • Measurement Uncertainty for Finite Quantum Observables 
    Schwonnek, René; Reeb, David; Werner, Reinhard F. (Basel : MDPI AG, 2016)
    Measurement uncertainty relations are lower bounds on the errors of any approximate joint measurement of two or more quantum observables. The aim of this paper is to provide methods to compute optimal bounds of this type. ...
  • Measurement uncertainty relations. 
    Busch, Paul; Lahti, Pekka; Werner, Reinhard F. (College Park, MD : American Institute of Physics, 2014)
    Measurement uncertainty relations are quantitative bounds on the errors in an approximate joint measurement of two observables. They can be seen as a generalization of the error/disturbance tradeoff first discussed ...
  • Proof of Heisenberg's error-disturbance relation 
    Busch, Paul; Lahti,Pekka; Werner, Reinhard F. (College Park, MD : American Physical Society, 2013)
    While the slogan “no measurement without disturbance” has established itself under the name of the Heisenberg effect in the consciousness of the scientifically interested public, a precise statement of this fundamental ...
  • Sharp uncertainty relations for number and angle 
    Busch, Paul; Kiukas, Jukka; Werner, Reinhard F. (College Park, MD : American Institute of Physics, 2018)
    We study uncertainty relations for pairs of conjugate variables like number and angle, of which one takes integer values and the other takes values on the unit circle. The translation symmetry of the problem in either ...
  • Uncertainty relations for angular momentum 
    Dammeier, Lars; Schwonnek, René; Werner, Reinhard F. (Bristol : Institute of Physics Publishing, 2015)
    In this work we study various notions of uncertainty for angular momentum in the spin-s representation of SU(2). We characterize the 'uncertainty regions' given by all vectors, whose components are specified by the variances ...
  • Uncertainty relations for general phase spaces 
    Werner, Reinhard F. (Beijing : Higher Education Press, 2016)
    We describe a setup for obtaining uncertainty relations for arbitrary pairs of observables related by a Fourier transform. The physical examples discussed here are the standard position and momentum, number and angle, ...
