基于ISWAP逻辑门的量子计算和纠缠态制备

Implementation of quantum computing and entanglement generation based on ISWAP logic gates

研究在多体系统中实现普适量子逻辑门以及制备量子纠缠态,从实验中最为常用的相互作用出发,通过控制两比特之间的耦合,直接构建ISAWP逻辑门,基于这个基本的逻辑操作,可以实现量子计算中最为普适的两比特逻辑门,同时还利用这种相互作用制备了多比特的W态和Cluster态.

In the paper, implementing universal quantum logic gates and generating quantum entangled states in many body system were investigated. From the most commonly used interaction in experiment, ISWAP gate could be obtained directly by controlling the coupling between arbitrary two qubits. Based on the gates, the other universal operations in quantum computation could be constructed, meanwhile, multi-qubit W entangled states and Cluster state also can be generated by the kind of interaction.
