    • Entanglement, local measurements and symmetry 

      Klyachko, A. A.; Shumovsky, A. S. (Institute of Physics Publishing, 2003)
      AbstractAdefinition of entanglement in terms of local measurements is discussed.Namely, the maximum entanglement corresponds to the states that cause thehighest level of quantum fluctuations in all local measurements ...
    • Maximum entanglement and its proper measure 

      Klyachko, A. A.; Shumovsky, A. S. (Institute of Physics, 2004)
      We discuss a definition of maximally entangled states in terms of maximum uncertainty of corresponding measurements. We describe a method of construction of bases of maximally entangled states. The entangled states that ...
    • Quantifying quantum information via uncertainties 

      Öztop, Barış; Klyachko, Alexander A.; Shumovsky, Alexander S. (OSA, 2007)
      We show, for a state ψ of a quantum system with the dynamic symmetry given by the Lie group G, total amount of quantum information and entanglement is provided by summarized uncertainty of basic observables.
    • Study of junction and bias parameters in readout of phase qubits 

      Zandi H.; Safaei, S.; Khorasani, S.; Fardmanesh, M. (2012)
      The exact numerical solution of the nonlinear Ginzburg-Landau equation for Josephson junctions is obtained, from which the precise nontrivial current density and effective potential of the Josephson junctions are found. ...
