On the quantification of entanglement in infinite-dimensional quantum systems
Jens Eisert, Christoph Simon, Martin B. Plenio
We investigate entanglement measures in the infinite-dimensional regime. First, we discuss the peculiarities that may occur if the Hilbert space of a bi-partite system is infinite-…
Quantum and classical correlations in quantum Brownian motion
J. Eisert, M. B. Plenio
We investigate the entanglement properties of the joint state of a distinguished quantum system and its environment in the quantum Brownian motion model. This model is a frequent s…
Conditions for the local manipulation of Gaussian states
J. Eisert, M. B. Plenio
We present a general necessary and sufficient criterion for the possibility of a state transformation from one mixed Gaussian state to another of a bi-partite continuous-variable s…
The asymptotic relative entropy of entanglement
K. Audenaert, J. Eisert, E. Jane +3
We present an analytical formula for the asymptotic relative entropy of entanglement for Werner states of arbitrary dimension. We then demonstrate its validity using methods from c…
