摘要:

研究了在双模驱动光腔中,由单个原子组成的开放量子系统中,如何实现量子反馈和概率纠错。通过条件测量和外加场的作用,可以操纵和控制基态叠加态,屏蔽相干性,修正量子误差。一个实验现实的情况下建模证明了在实验室实现的建议的鲁棒性。

英文摘要:

It is shown how to implement quantum feedback and probabilistic error correction in an open quantum system consisting of a single atom, with ground- and excited-state Zeeman structure, in a driven two-mode optical cavity. The ground state superposition is manipulated and controlled through conditional measurements and external fields, which shield the coherence and correct quantum errors. Modeling of an experimentally realistic situation demonstrates the robustness of the proposal for realization in the laboratory.
