二维和三维结构中的理想态转移

Perfect State Transfer in Two and Three Dimensional Structures

Vahid Karimipour, Mahdi Sarmadi Rad, Marzieh Asoudeh

摘要:

本文介绍了一种在规则的二维和三维结构中实现完全态转移的方案。晶格上的相互作用是XX自旋型的,具有均匀耦合。在二维中,该结构是六边形晶格,在三维中,它由在任意点处彼此连接的六边形平面组成。我们将证明,与其他方案相比,i)路由所需的控制要少得多,ii)全局控制的代数非常简单,iii)同一种控制可以向内置读写(RW)头上传和下载量子位状态。首先介绍了一种量子开关,我们称之为Hadamard开关,因为它的操作依赖于四维Hadamard矩阵的存在。

英文摘要:

We introduce a scheme for perfect state transfer in regular two and three dimensional structures. The interactions on the lattices are of XX spin type with uniform couplings. In two dimensions the structure is a hexagonal lattice and in three dimensions it consists of hexagonal planes joined to each other at arbitrary points. We will show that compared to other schemes, i) much less control is needed for routing, ii) the algebra of global control is quite simple, iii) the same kind of control can upload and download qubit states to or from built-in Read-Write (RW) heads. Pivotal use is made of a quantum switch which we introduce and call it Hadamard switch, since its operation depends on the existence of a Hadamard matrix in four dimensions.
