无限维纯二体态的纠缠可转换性

Entanglement convertibility for infinite dimensional pure bipartite states

Masaki Owari, Keiji Matsumoto, Mio Murao

摘要:

结果表明,当维数从有限变到无限时,纯二体态在随机局域操作和经典通信下的序性质发生了根本性的变化。与不存在纯不可比状态的有限维系统相反,即使在能量有界和信息交换有限的条件下,无限维系统也存在无限多个相互SLOCC不可比状态。这些结果表明,希尔伯特空间的无限维的影响,“无限工作空间”的属性,即使在物理相关的无限维系统中仍然存在。

英文摘要:

It is shown that the order property of pure bipartite states under SLOCC (stochastic local operations and classical communications) changes radically when dimensionality shifts from finite to infinite. In contrast to finite dimensional systems where there is no pure incomparable state, the existence of infinitely many mutually SLOCC incomparable states is shown for infinite dimensional systems even under the bounded energy and finite information exchange condition. These results show that the effect of the infinite dimensionality of Hilbert space, the ``infinite workspace'' property, remains even in physically relevant infinite dimensional systems.
