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…
