论文摘要
除了其基本重要性外，非股展度还发现了许多潜在的量子技术应用。最近，已经提出了许多量子系统来实现非循环系统，但是由于人工系统中所需的周期性相互作用或固态材料中的操作困难，稳定的非重生过程在实验上仍然很困难。在这里，我们根据常规的搅拌设置提出了一种新型的相互作用诱导的非逆局性操作，该设置消除了需要周期性相互作用的实验难度，因此在各种量子系统中可以直接实现。此外，我们还说明了我们对三个耦合超导式传输的链条的提议，这可以导致具有高忠诚度的非重点循环器，而没有环形耦合构型，如先前的方案或实现。因此，我们的协议提供了一种有希望的方法来探索基本的非重生量子物理学以及实现非近代量子设备。
Besides its fundamental importance, non-reciprocity has also found many potential applications in quantum technology. Recently, many quantum systems have been proposed to realize non-reciprocity, but stable non-reciprocal process is still experimentally difficult in general, due to the needed cyclical interactions in artificial systems or operational difficulties in solid state materials. Here, we propose a new kind of interaction induced non-reciprocal operation, based on the conventional STIRAP setup, which removes the experimental difficulty of requiring cyclical interaction, and thus it is directly implementable in various quantum systems. Furthermore, we also illustrate our proposal on a chain of three coupled superconducting transmons, which can lead to a non-reciprocal circulator with high fidelity without a ring coupling configuration as in the previous schemes or implementations. Therefore, our protocol provides a promising way to explore fundamental non-reciprocal quantum physics as well as realize non-reciprocal quantum device.
