Gaussian relative entropy of entanglement
For two gaussian states with given correlation matrices, in order that relative entropy between them is practically calculable, I in this paper describe the ways of transforming the correlation matrix to matrix in the exponential density operator. Gaussian relative entropy of entanglement is proposed as the minimal relative entropy of the gaussian state with respect to separable gaussian state ...
متن کاملAsymptotic relative entropy of entanglement.
We present an analytical formula for the asymptotic relative entropy of entanglement with respect to positive partial transpose states for Werner states of arbitrary dimension. We then demonstrate its validity using methods from convex optimization. This is the first case in which the asymptotic value of a subadditive entanglement measure has been calculated.
متن کاملInformation, relative entropy of entanglement, and irreversibility.
Previously proposed measures of entanglement, such as entanglement of formation and assistance, are shown to be special cases of the relative entropy of entanglement. The difference between these measures for an ensemble of mixed states is shown to depend on the availability of classical information about particular members of the ensemble. Based on this, relations between relative entropy of e...
متن کاملRelative entropy of entanglement of rotationally invariant states
Quantum entanglement has played a significant role in the field of quantum information and quantum computation [1]. This attracts an increasing interest in the study of quantification of entanglement for any quantum state. Although a lot of entanglement measures have been proposed for a generic mixed state, only partial solutions such as entanglement of formation (EoF) for two qubits [2, 3], ar...
متن کاملErratum: Numerical estimation of the relative entropy of entanglement
It has come to the attention of the authors that the MATLAB code1 provided in the original paper does not work as stated. Although the code presented in the original paper was only intended to act as a guide that other researchers might follow for writing their own codes, for the sake of completeness, the present Erratum presents a fully functional code for correctly estimating the relative ent...
