最近已经提出了适合于与飞行电子相互作用的超导量子位装置[Okamoto和Nagatani，Appl. Phys. Lett. 104，062604（2014）APPLAB0003-695110.1063/1.4865244]。无论是顺时针还是逆时针方向的半磁通量量子环编码一个量子比特，它自然地与任何具有任意动能的单个带电粒子相互作用。在这里，设备的属性，错误的来源，和可能的应用程序进行了详细研究。特别是，应用包括带电粒子的检测基本上不施加经典力。此外，量子态可以在所提出的设备的阵列和带电粒子之间转移。
A superconducting qubit device suitable for interacting with a flying electron has recently been proposed [Okamoto and Nagatani, Appl. Phys. Lett. 104, 062604 (2014)APPLAB0003-695110.1063/1.4865244]. Either a clockwise or counterclockwise directed loop of half magnetic flux quantum encodes a qubit, which naturally interacts with any single charged particle with arbitrary kinetic energy. Here, the device's properties, sources of errors, and possible applications are studied in detail. In particular, applications include detection of a charged particle essentially without applying a classical force to it. Furthermore, quantum states can be transferred between an array of the proposed devices and the charged particle.
