    • Entanglement and perfect discrimination of a class of multiqubit states by local operations and classical communication 

      Bandyopadhyay, Somshubhro (AMER PHYSICAL SOC, 2010-02-01)
      It is shown that while entanglement ensures difficulty in discriminating a set of mutually orthogonal states perfectly by local operations and classical communication (LOCC), entanglement content does not. In particular, ...

    • Entanglement cost of nonlocal measurements 

      Bandyopadhyay, Somshubhro; Brassard, G.; Kimmel, S.; Wootters, W. K. (AMER PHYSICAL SOC, 2009-07-01)
      For certain joint measurements on a pair of spatially separated particles, we ask how much entanglement is needed to carry out the measurement exactly. For a class of orthogonal measurements on two qubits with partially ...

    • Entanglement cost of two-qubit orthogonal measurements 

      Bandyopadhyay, Somshubhro; Rahaman, Ramij; Wootters, William K. (IOP Publishing, 2010-11-12)
      The ‘entanglement cost’ of a bipartite measurement is the amount of shared entanglement two participants need to use up in order to carry out the given measurement by means of local operations and classical communication. We ...
