Abstract

我们与 bequsi 相互作用在一个由两部组成的 3 水平系统调查 2-qutrit 逻辑门的实现。根据矩阵的 Cartan 分解， 2-qutrit 的单一的矩阵是进一系列可实现的矩阵的产品的 factorized。它等价于在系统，和控制目标上施加某个控制域被控制脉搏的一个序列通常获得。逻辑门被成为第一的 2-qutrit 的实现的一般讨论，然后实现第三交换门，第三的门明确地被讨论，并且控制脉搏的序列和实现这些门的飘移过程被给。

Realization of Two-Qutrit Quantum Gates with Control Pulses

Jie Zhang, Yao-Min Di, Hai‐Rui Wei

We investigate the realization of 2-qutrit logic gate in a bipartite 3-level system with qusi-Ising interaction. On the basis of Cartan decomposition of matrices, the unitary matrices of 2-qutrit are factorized into products of a series of realizable matrices. It is equivalent to exerting a certain control field on the system, and the control goal is usually gained by a sequence of control pulses. The general discussion on the realization of 2-qutrit logic gate is made first, and then the realization of the ternary SWAP gate and the ternary gate are discussed specifically, and the sequences of control pulses and drift processes implementing these gates are given.
