复曲面簇:多体量子系统的简单组合和几何结构

Toric varieties: Simple combinatorial and geometrical structure of multipartite quantum systems

Hoshang Heydari

摘要:

我们基于复曲面簇的构造研究了多体态的几何结构。我们证明了复曲面簇表示一般纯态空间,而投射复曲面簇定义了多比特态的可分集空间。我们还详细讨论了单比特、双比特、三比特和多比特态的构造.这种构造给出了多体量子系统的几何结构的非常简单和优雅的视觉表示。

英文摘要:

We investigate the geometrical structure of multipartite states based on the construction of toric varieties. We show that the toric variety represents the space of general pure states and projective toric variety defines the space of separable set of multi-qubits states. We also discuss in details the construction of single-, two-, three-, and multi- qubits states. This construction gives a very simple and elegant visual representation of the geometrical structure of multipartite quantum systems.
