QUANTUM PHASE-CHARGE COUPLED DEVICE

摘要

A superconducting structure that includes a mesoscopic phase device (110, 310) and a mesoscopic charge device (120). The superconducting structure further includes a mechanism for coupling the mesoscopic phase device and the mesoscopic charge device so that the quantum state of the mesoscopic phase device and the quantum state of the mesoscopic charge device interact. In another aspect, the superconducting structure includes a mechanism for reading out the quantum state of the mesoscopic charge device. Quantum computation operations can be performed using the structure.
