稳定子态的同调不变量

Homological invariants of stabilizer states

Klaus Wirthmüller

摘要:

我们提出了一种新的多方稳定态关于局部Clifford等价的不变量。这些同调不变量是离散的实体,根据一个状态相对于任意分组的各方所享有的纠缠来定义,它们可以被认为是以定性的方式反映纠缠。我们调查的不变量的基本性质,并将它们与已知的结果GHZ状态的提取。

英文摘要:

We propose a new kind of invariant of multi-party stabilizer states with respect to local Clifford equivalence. These homological invariants are discrete entities defined in terms of the entanglement a state enjoys with respect to arbitrary groupings of the parties, and they may be thought of as reflecting entanglement in a qualitative way. We investigate basic properties of the invariants and link them with known results on the extraction of GHZ states.
