A Meaner King uses Biased Bases

M. Reimpell, R. F. Werner

The mean king problem is a quantum mechanical retrodiction problem, in which Alice has to name the outcome of an ideal measurement on a d-dimensional quantum system, made in one of…

Estimating entanglement measures in experiments

O. Gühne, M. Reimpell, R. F. Werner

We present a method to estimate entanglement measures in experiments. We show how a lower bound on a generic entanglement measure can be derived from the measured expectation value…

Comment on "Optimum Quantum Error Recovery using Semidefinite Programming"

M. Reimpell, R. F. Werner, K. Audenaert

In a recent paper ([1]=quant-ph/0606035) it is shown how the optimal recovery operation in an error correction scheme can be considered as a semidefinite program. As a possible fut…

Permutation and Its Partial Transpose

Yong Zhang, Louis H. Kauffman, Reinhard F. Werner

Permutation and its partial transpose play important roles in quantum information theory. The Werner state is recognized as a rational solution of the Yang--Baxter equation, and th…

Reexamination of Quantum Bit Commitment: the Possible and the Impossible

Giacomo Mauro D'Ariano, Dennis Kretschmann, Dirk Schlingemann +1

Bit commitment protocols whose security is based on the laws of quantum mechanics alone are generally held to be impossible. In this paper we give a strengthened and explicit proof…

The Information-Disturbance Tradeoff and the Continuity of Stinespring's Representation

Dennis Kretschmann, Dirk Schlingemann, Reinhard F. Werner

Stinespring's dilation theorem is the basic structure theorem for quantum channels: it states that any quantum channel arises from a unitary evolution on a larger system. Here we p…
