摘　　要：多比特量子逻辑门是实现量子计算机的基本要素之一。一个通用的量子逻辑门在量子纠错、量子算法等领域都有广泛的应用前景。本文提出了一种利用里德堡原子阻塞效应来实现的非组合式多比特量子逻辑门的构建方法,实现了一个高保真、鲁棒性强、可扩展的通用多比特量子逻辑门,并通过数值模拟验证了逻辑门的保真度和鲁棒性。Multiple-qubit quantum logic gate is one of the basic elements to realize quantum computer.An unitary quantum logic gate has a wide application prospect in quantum error correction,quantum algorithm and other fields.In this paper,a non-combinatorial multiple-qubit quantum logic gate based on Rydberg atom blocked effect is proposed,and a high-fidelity,robust and scalable unitary multiple-qubit quantum logic gate is realized,and the fidelity and robust of the gate are verified by numerical simulation.
