We introduce a "microcanonical" measure (complying with the "general canonical principle") over the second moments of pure bosonic Gaussian states under an energy constraint. We determine the average fidelity for the teleportation of states distributed according to such a measure and compare it to a threshold obtained from a feasible classical strategy. Furthermore, we show that, under the proposed measure, the distribution of the entanglement concentrates around a finite value at the thermodynamical limit and, in general, the typical entanglement of Gaussian states with maximal energy E is not close to the maximum allowed by E.

Relations between entanglement, Bell-inequality violation and teleportation fidelity for the two-qubit X states
基于接收机Bob可以应用任何酉变换的假设，Horodecki { \it et al.} [Phys. Lett. A { \bf 222}，21（1996）]证明了任何违反Bell-CHSH不等式的两自旋1/2混合态都可用于隐形传态。在这里，我们进一步表明，任何违反Bell-CHSH不等式的X状态也可以用于非经典隐形传态，即使鲍勃只能执行身份或泡利旋转操作。此外，我们还证明了通过Bob的任意变换和通过唯一恒等式或泡利旋转可实现的两个平均相似度之间的最大差异是1/9。
