连续变量三重非线性的三重纠缠和Einstein-Podolsky-Rosen关联

Continuous variable tripartite entanglement and Einstein-Podolsky-Rosen correlations from triple nonlinearities

M. K. Olsen, A. S. Bradley, M. D. Reid

摘要:

利用van Look-Furusawa不等式,我们从理论上比较了三个并行的$χ^{(2)}$非线性和三个独立的压缩态在分束器上混合时的三重纠缠.我们还定义了爱因斯坦-波多尔斯基-罗森佯谬的三模推广,这是证明密度矩阵不可分性的一种替代方法。

英文摘要:

We compare theoretically the tripartite entanglement available from the use of three concurrent $χ^{(2)}$ nonlinearities and three independent squeezed states mixed on beamsplitters, using the van Loock-Furusawa inequalities. We also define three-mode generalisations of the Einstein-Podolsky-Rosen paradox which are an alternative for demonstrating the inseparability of the density matrix.
