Evenly distributed unitaries: on the structure of unitary designs
D. Gross, K. Audenaert, J. Eisert
We clarify the mathematical structure underlying unitary -designs. These are sets of unitary matrices, evenly distributed in the sense that the average of any -th order polyn…
A Sharp Fannes-type Inequality for the von Neumann Entropy
Koenraad M. R. Audenaert
We derive an inequality relating the entropy difference between two quantum states to their trace norm distance, sharpening a well-known inequality due to M. Fannes. In our inequal…
The Quantum Chernoff Bound
K. M. R. Audenaert, J. Calsamiglia, Ll. Masanes +4
We consider the problem of discriminating two different quantum states in the setting of asymptotically many copies, and determine the optimal strategy that minimizes the total pro…
When are correlations quantum? -- Verification and quantification of entanglement by simple measurements
K. M. R. Audenaert, M. B. Plenio
The verification and quantification of experimentally created entanglement by simple measurements, especially between distant particles, is an important basic task in quantum proce…
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…
