标题： Driving two atoms in an optical cavity into an entangled steady state using engineered decay

摘要： 我们提出多种方案，用于在光学腔中制备两个原子的最大纠缠稳态。 利用腔光子损耗和自发辐射的自然衰减过程，我们使用有效算符形式来识别和设计有效的衰减过程，这些过程使两个原子达到纠缠稳态作为耗散时间演化的唯一不动点。 我们研究了在当今和未来腔量子电动力学系统中实现我们方案的各种关键方面，并解析推导出我们协议的最佳参数、误差尺度和收敛速度。 我们的研究表明，我们的方案在现有腔实验中表现出良好的性能，并且保真度和速度相对于腔参数具有有利的缩放特性。 显示英文摘要

摘要： We propose various schemes for the dissipative preparation of a maximally entangled steady state of two atoms in an optical cavity. Harnessing the natural decay processes of cavity photon loss and spontaneous emission, we use an effective operator formalism to identify and engineer effective decay processes, which reach an entangled steady state of two atoms as the unique fixed point of the dissipative time evolution. We investigate various aspects that are crucial for the experimental implementation of our schemes in present-day and future cavity quantum electrodynamics systems and analytically derive the optimal parameters, the error scaling and the speed of convergence of our protocols. Our study shows promising performance of our schemes for existing cavity experiments and favorable scaling of fidelity and speed with respect to the cavity parameters.
