Non-commutativity measure of quantum discord
Quantum discord is a manifestation of quantum correlations due to non-commutativity rather than entanglement. Two measures of quantum discord by the amount of non-commutativity via the trace norm and the Hilbert-Schmidt norm respectively are proposed in this paper. These two measures can be calculated easily for any state with arbitrary dimension. It is shown by several examples that these meas...
متن کاملQuantum Horizons and Space-Time Non-Commutativity
We study dynamics of a scalar field in the near-horizon region described by a static Klein-Gordon operator which is the Hamiltonian of the system. The explicite construction of a time operator near-horizon is given and its self-adjointness discussed. ⋆ Expanded version of a poster presented at the 5 European Advanced Study Conference in Ancient Olympia, Greece, May 2004. Preprint submitted to E...
متن کاملCommutativity of quantum weakest preconditions
The notion of quantum weakest precondition was introduced by D’Hondt and P. Panangaden (Mathematical Structures in Computer Science 16(2006)429-451), and they presented a representation of weakest precondition of a quantum program in the operatorsum form. In this letter, we give an intrinsic characterization of the weakest precondition of a quantum program given in a systemenvironment model. Fu...
متن کاملNon–commutativity in Teleportation
We show, using the no–disentanglement theorem, that to teleport (exactly) any set of non–commuting states (i.e., a set containing at least two non–commuting states), it is necessary to have an entangled channel. We further show that to teleport any set of commuting states it is sufficient to have a classically correlated channel. Using this result we provide a simple proof of the fact that any ...
متن کاملTime dependence and (non)commutativity of symmetries of evolution equations
We present easily verifiable sufficient conditions of time-independence and commutativity for local and nonlocal symmetries for a large class of homogeneous (1+1)-dimensional evolution systems. In contrast with the majority of known results, the verification of our conditions does not require the existence of master symmetry or hereditary recursion operator for the system in question. We also g...
