چکیده
We consider the problem of comparison of two entangled states by local operations and classical communication, i. e. whether or not two entangled states are the same. We show that the optimal bound of state comparison by global measurements can also be achieved by local operations and classical communication both in the sense of conclusive comparison and inconclusive one. 03.67.-a, 03.65.Ta, 42.50.Dv Typeset using REVTEX Email: [email protected] Email: [email protected]

We investigate the teleportation of the bipartite entangled states through two equally noisy quantum channels, namely mixture of Bell states. There is a particular mixed state channel for which all pure entanglement in a known Schmidt basis remain entangled after teleportation and it happens till the channel state remains entangled. Werner state channel lacks both these features. The relation o...

A class of self-similar sets of entangled quantum states is introduced, for which a recursive definition is provided. These sets, the “Bell gems,” are defined by the subsystem exchange symmetry characteristic of the Bell states. Each Bell gem is shown to be an orthonormal basis of maximally entangled elements.

We use some general results regarding positive maps to exhibit examples of non-decomposable maps and 2 ×2N , N ≥ 2, bound entangled states, e.g. non distillable bipartite states of N+N qubits.

We consider explicitly two examples of d-dimensional quantum channels with correlated noise and show that, in agreement with previous results on Pauli qubit channels, there are situations where maximally entangled input states achieve higher values of the output mutual information than product states. We obtain a strong dependence of this effect on the nature of the noise correlations as well a...
