Continuous variable multipartite entanglement and optical implementations of quantum communication networks

Yimin Lian, Changde Xie, Kunchi Peng

A variety of optical quantum information networks based on the multipartite entanglement of amplitude and phase quadratures of an electromagnetic field have been proposed and experimentally realized in recent years. The multipartite entanglement of optical continuous variables provides flexible and reliable quantum resources for developing unconditional quantum information networks. In this paper, we review the generation schemes of the multipartite entangled states of optical continuous quantum variables and some applications in the quantum communication networks with emphasis on the experimental implementations.

Continuous-variable multipartite unlockable bound entangled Gaussian states

Jing Zhang

We investigate continuous-variable (CV) multipartite unlockable bound entangled states. Comparing with the qubit multipartite unlockable bound entangled states, CV multipartite unlockable bound entangled states present some new and different properties. CV multipartite unlockable bound entangled states may serve as a useful quantum resource for new multiparty communication schemes. The experimental protocol for generating CV unlockable bound entangled states is proposed with a setup that is, at present, accessible.

Generating scalable multipartite entanglement and non-Gaussian states of light using nonlinear concurrences and cascades

Raphael C. Pooser, Olivier Pfister

The generation of continuous-variable (CV) scalable multipartite entanglement and non-Gaussian states is important for quantum information, in particular quantum computing. Non-Gaussian Wigner functions as well as macroscopic scaling of multipartite entanglement are both necessary ingredients for a CV quantum computer [1]. As a result it is necessary to find a reliable way to produce such states in a compact, manageable manner. Our group has shown that the use of concurrent second order nonlinearities and continuous variables can solve the scalability problem [2]. Second order cascaded nonlinearities could also be used in an optical parametric oscillator (OPO) to produce an effective third-order Hamiltonian, which is needed to produce non-Gaussian states.
