Gaussian Entanglement of Formation
M. M. Wolf, G. Giedke, O. Krueger +2
We introduce a Gaussian version of the entanglement of formation adapted to bipartite Gaussian states by considering decompositions into pure Gaussian states only. We show that thi…
Iterative Optimization of Quantum Error Correcting Codes
M. Reimpell, R. F. Werner
We introduce a convergent iterative algorithm for finding the optimal coding and decoding operations for an arbitrary noisy quantum channel. This algorithm does not require any err…
Entanglement of formation for symmetric Gaussian states
G. Giedke, M. M. Wolf, O. Krueger +2
We show that for a fixed amount of entanglement, two-mode squeezed states are those that maximize Einstein-Podolsky-Rosen-like correlations. We use this fact to determine the entan…
On the irreversibility of entanglement distillation
K. G. H. Vollbrecht, R. F. Werner, M. M. Wolf
We investigate the irreversibility of entanglement distillation for a symmetric d-1 parameter family of mixed bipartite quantum states acting on Hilbert spaces of arbitrary dimensi…
