在这项工作中，我们提出了如何加载和操纵的约瑟夫森结环中的手征态在所谓的transmon制度。我们通过它们在时间反演和宇称变换下的对称性来表征这些态。我们描述了一个明确的协议来加载和检测一组现实的电路参数内的状态，并显示模拟，揭示了手性的性质。最后，我们探讨了这些国家在量子技术的非互易设备的效用。
In this work, we propose how to load and manipulate chiral states in a Josephson junction ring in the so-called transmon regime. We characterize these states by their symmetry properties under time-reversal and parity transformations. We describe an explicit protocol to load and detect the states within a realistic set of circuit parameters and show simulations that reveal the chiral nature. Finally, we explore the utility of these states in quantum technological nonreciprocal devices.
