Universal Quantum Estimator
Artur K. Ekert, Carolina Moura Alves, Daniel K. L. Oi +3
We present a simple device based on the controlled-SWAP gate that performs quantum state tomography. It can also be used to determine maximum and minimum eigenvalues, expectation v…
Mixed-state entanglement and quantum communication
Michal Horodecki, Pawel Horodecki, Ryszard Horodecki
We present basics of mixed-state entanglement theory. The first part of the article is devoted to mathematical characterizations of entangled states. In second part we discuss the…
Concurrence in arbitrary dimensions
Piotr Badziag, Piotr Deuar, Michal Horodecki +2
We argue that a complete characterisation of quantum correlations in bipartite systems of many dimensions may require a quantity which, even for pure states, does not reduce to a s…
Classical capacity of a noiseless quantum channel assisted by noisy entanglement
Michal Horodecki, Pawel Horodecki, Ryszard Horodecki +2
We derive the general formula for the capacity of a noiseless quantum channel assisted by an arbitrary amount of noisy entanglement. In this capacity formula, the ratio of the quan…
A uniqueness theorem for entanglement measures
Oliver Rudolph
We obtain a mathematically simple characterization of all functionals coinciding with the von Neumann reduced entropy on pure states based on the Khinchin-Faddeev axiomatization of…
Dynamical description of quantum computing: generic nonlocality of quantum noise
Robert Alicki, Michal Horodecki, Pawel Horodecki +1
We develop dynamical non-Markovian description of quantum computing in weak coupling limit, in lowest order approximation. We show that long range memory of quantum reservoir produ…
