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…
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.
Entanglement capabilities of non-local Hamiltonians
W. Dür, G. Vidal, J. I. Cirac +2
We quantify the capability of creating entanglement for a general physical interaction acting on two qubits. We give a procedure for optimizing the generation of entanglement. We a…
Reversible combination of inequivalent kinds of multipartite entanglement
G. Vidal, W. Dür, J. I. Cirac
We present a family of tri-partite entangled states that, in an asymptotical sense, can be reversibly converted into EPR states shared by only two of parties (say B and C), and tri…
