Abstract

The implementation of a quantum logic gate in a system of cold atoms in optical microtraps is analyzed. The dynamics of two spin qubits is simulated, and a number of processes that limit the efficiency of entanglement based on the Rydberg blockade effect are considered. A geometry of two-photon excitation of Rydberg states of atoms is proposed that makes it possible to increase the robustness of the system to variations in a number of parameters and to reduce losses associated with the incoherent scattering of the driving field.

基于Rydberg阻塞效应的纠缠逻辑门优化
分析了光学微rap中冷原子系统中量子逻辑门的实现。模拟了两个自旋量子位的动力学,并考虑了基于里德伯阻塞效应的许多限制纠缠效率的过程。提出了原子Rydberg态的双光子激发的几何结构,该几何结构可以提高系统对许多参数变化的鲁棒性,并减少与驱动场的非相干散射相关的损耗。
