Quantum Lost and Found
M. Gregoratti, R. F. Werner
We consider the problem of correcting the errors incurred from sending classical or quantum information through a noisy quantum environment by schemes using classical information o…
Entanglement Properties of the Harmonic Chain
K. Audenaert, J. Eisert, M. B. Plenio +1
We study the entanglement properties of a closed chain of harmonic oscillators that are coupled via a translationally invariant Hamiltonian, where the coupling acts only on the pos…
Asymptotic Relative Entropy of Entanglement for Orthogonally Invariant States
K. Audenaert, B. De Moor, K. G. H. Vollbrecht +1
For a special class of bipartite states we calculate explicitly the asymptotic relative entropy of entanglement with respect to states having a positive partial transp…
Hiding classical data in multi-partite quantum states
T. Eggeling, R. F. Werner
We present a general technique for hiding a classical bit in multipartite quantum states. The hidden bit, encoded in the choice of one of two possible density operators, cannot be…
The Quantum Monty Hall Problem
G. M. D'Ariano, R. D. Gill, M. Keyl +3
We consider a quantum version of a well-known statistical decision problem, whose solution is, at first sight, counter-intuitive to many. In the quantum version a continuum of poss…
