论文摘要
腐烂会影响所有自然或人造的量子系统，并且是阻碍量子技术的主要障碍。从理论上讲，对于bose凝结环境中的rydberg量子，实验可以成像具有反谐压的核心的系统 - 环境界面。冷凝环境的高精度吸收图像将能够捕获瞬态信号，这些信号显示了在环境中的介质纠缠状态的实时构建。在冷凝水本身以外的其他分流源可以启动之前，这是可能的，因为可以通过选择激发的rydberg principal量子数νν来调整量子级的时间尺度。成像界面将允许详细探讨开放量子系统概念，并可能在具有非马克维亚环境的挑战性场景中为连贯保护提供指导。
Decoherence affects all quantum systems, natural or artificial, and is the primary obstacle impeding quantum technologies. We show theoretically that for a Rydberg qubit in a Bose condensed environment, experiments can image the system-environment interface that is central for decoherence. High precision absorption images of the condensed environment will be able to capture transient signals that show the real time build up of a mesoscopic entangled state in the environment. This is possible before decoherence sources other than the condensate itself can kick in, since qubit decoherence time-scales can be tuned from the order of nanoseconds to microseconds by choice of the excited Rydberg principal quantum number ν. Imaging the interface will allow detailed explorations of open quantum system concepts and may offer guidance for coherence protection in challenging scenarios with non-Markovian environments.
