Multi-Particle Entanglement Purification Protocols
M. Murao, M. B. Plenio, S. Popescu +2
Purification schemes for multi-particle entangled states cannot be treated as straightforward extensions of those for two particles because of the lack of symmetry they possess. We…
Implementations of Quantum Logic: Fundamental and Experimental Limits
S. Bose, P. L. Knight, M. Murao +2
Quantum information processing rests on our ability to manipulate quantum superpositions through coherent unitary transformations. In reality the quantum information processor (a l…
A Multiparticle Generalization of Entanglement Swapping
S. Bose, V. Vedral, P. L. Knight
We generalize the procedure of entanglement swapping to obtain a scheme for manipulating entanglement in multiparticle systems. We describe how this scheme allows to establish mult…
Entanglement Measures and Purification Procedures
V. Vedral, M. B. Plenio
We generalize previously proposed conditions each measure of entanglement has to satisfy. We present a class of entanglement measures that satisfy these conditions and show that th…
Statistical Inference, Distinguishability of Quantum States, And Quantum Entanglement
V. Vedral, M. B. Plenio, K. Jacobs +1
We argue from the point of view of statistical inference that the quantum relative entropy is a good measure for distinguishing between two quantum states (or two classes of quantu…
Quantifying Entanglement
V. Vedral, M. B. Plenio, M. A. Rippin +1
We present conditions every measure of entanglement has to satisfy and construct a whole class of 'good' entanglement measures. The generalization of our class of entanglement meas…
