Optimal estimation of quantum dynamics
A. Acin, E. Jane, G. Vidal
We construct the optimal strategy for the estimation of an unknown unitary transformation . This includes, in addition to a convenient measurement on a probe system, fi…
Three-qubit pure-state canonical forms
A. Acin, A. Andrianov, E. Jane +1
In this paper we analyze the canonical forms into which any pure three-qubit state can be cast. The minimal forms, i.e. the ones with the minimal number of product states built fro…
Three-party entanglement from positronium
A. Acin, J. I. Latorre, P. Pascual
The decay of ortho-positronium into three photons produces a physical realization of a pure state with three-party entanglement. Its quantum correlations are analyzed using recent…
Optimal distillation of a GHZ state
A. Acin, E. Jane, W. Dur +1
We present the optimal local protocol to distill a Greenberger-Horne-Zeilinger (GHZ) state from a single copy of any pure state of three qubits.
Generalized Schmidt decomposition and classification of three-quantum-bit states
A. Acin, A. Andrianov, L. Costa +3
We prove for any pure three-quantum-bit state the existence of local bases which allow to build a set of five orthogonal product states in terms of which the state can be written i…
