Multiple-copy entanglement transformation and entanglement catalysis

We prove that any multiple-copy entanglement transformation fS. Bandyopadhyay, V. Roychowdhury, and U. Sen, Phys. Rev. A 65, 052315 s2002dg can be implemented by a suitable entanglement-assisted local transformation fD. Jonathan and M. B. Plenio, Phys. Rev. Lett. 83, 3566 s1999dg. Furthermore, we show that the combination of multiple-copy entanglement transformation and the entanglement-assiste...

Double entanglement and quantum cryptography

We propose a quantum transmission based on bi-photons which are doubly-entangled both in polarisation and phase. This scheme finds a natural application in quantum cryptography, where we show that an eventual eavesdropper is bound to introduce a larger error on the quantum communication than for a single entangled bi-photon communication, when he steels the same information.

Trade-off between multiple-copy transformation and entanglement catalysis

We demonstrate that multiple copies of a bipartite entangled pure state may serve as a catalyst for certain entanglement transformations while a single copy cannot. Such a state is termed a “multiple-copy catalyst” for the transformations. A trade-off between the number of copies of source state and that of the catalyst is also observed. These results can be generalized to probabilistic entangl...

An Equivalence of Entanglement-Assisted Transformation and Multiple-Copy Entanglement Transformation

We examine the powers of entanglement-assisted transformation and multiple-copy entanglement transformation. First, we find a sufficient condition of when a given catalyst is useful in producing another specific target state. As an application of this condition, for any non-maximally entangled bipartite pure state and any integer n not less than 4, we are able to explicitly construct a set of n...

Entanglement and the Kondo effect in double quantum dots

We investigate entanglement between electrons in serially coupled double quantum dots attached to non interacting leads. In addition to local repulsion we consider the influence of capacitive inter-dot interaction. We show how the competition between extended Kondo and local singlet phases determines the ground state and thereby the entanglement.
