一维光晶格量子计算

Quantum Computation with a One-Dimensional Optical Lattice

Jiannis Pachos, Peter L. Knight

摘要:

提出了一种经济的动力学控制方案,在一维光晶格上进行量子计算,其中每个原子编码一个量子比特。该模型是基于原子之间的晶格相邻网站的隧道跃迁。它们可以被外部激光束激活,从而产生双量子位相位门或交换相互作用。提出了一种不需要单个原子寻址而只需单脉冲激光的Toffoli门的实现方法。

英文摘要:

We present an economical dynamical control scheme to perform quantum computation on a one dimensional optical lattice, where each atom encodes one qubit. The model is based on atom tunneling transitions between neighboring sites of the lattice. They can be activated by external laser beams resulting in a two-qubit phase gate or in an exchange interaction. A realization of the Toffoli gate is presented which requires only a single laser pulse and no individual atom addressing.
