Multipartite entanglement for continuous variables: A quantum teleportation network
نویسندگان
چکیده
We show that one single-mode squeezed state distributed among N parties using linear optics suffices to produce a truly N-partite entangled state for any nonzero squeezing and arbitrarily many parties. From this N-partite entangled state, via quadrature measurements of N-2 modes, bipartite entanglement between any two of the N parties can be "distilled," which enables quantum teleportation with an experimentally determinable fidelity better than could be achieved in any classical scheme.

Quantum Teleportation with Continuous Variables: a survey
Very recently we have witnessed a new development of quantum information, the so-called continuous variable (CV) quantum information theory. Such a further development has been mainly due to the experimental and theoretical advantages offered by CV systems, i.e., quantum systems described by a set of observables, like position and momentum, which have a continuous spectrum of eigenvalues. Accor...
متن کاملDealing with entanglement of continuous variables: Schmidt decomposition with discrete sets of orthogonal functions
Bipartite and multipartite entanglement is one of the features that give rise to many of the developments of quantum computation and information, like quantum teleportation [1, 2] and quantum cryptography [3, 4], among others [5]. The evaluation of the entanglement of a composite state is thus a main task to be done. For this purpose, the Schmidt decomposition [6, 7] has proven to be a valuable...
متن کاملBipartite and Multipartite Entanglement of Gaussian States
In this chapter we review the characterization of entanglement in Gaus-sian states of continuous variable systems. For two-mode Gaussian states, we discuss how their bipartite entanglement can be accurately quantified in terms of the global and local amounts of mixedness, and efficiently estimated by direct measurements of the associated purities. For multimode Gaussian states endowed with loca...
متن کاملEquivalence between entanglement and the optimal fidelity of continuous variable teleportation.
We devise the optimal form of Gaussian resource states enabling continuous-variable teleportation with maximal fidelity. We show that a nonclassical optimal fidelity of N-user teleportation networks is necessary and sufficient for N-party entangled Gaussian resources, yielding an estimator of multipartite entanglement. The entanglement of teleportation is equivalent to the entanglement of forma...
متن کاملMultipartite entangled coherent states
We propose a scheme for generating multipartite entangled coherent states via entanglement swapping, with an example of a physical realization in ion traps. Bipartite entanglement of these multipartite states is quantified by the concurrence. We also compute multipartite entanglement for certain systems. Finally we establish that these results for entanglement can be applied to more general mul...
