| 英文摘要 | Abstract two-junction squids with negative mutual inductance between their two arms, called nsquids, have been proposed for significantly improving quantum information transfer but their quantum nature has not been experimentally demonstrated. we have designed, fabricated, and characterized superconducting nsquid qubits. our results provide clear evidence of the quantum coherence of the device, whose properties are well described by theoretical calculations using parameters determined from spectroscopic measurement. in addition to their future application for fast quantum information transfer, the nsquid qubits exhibit rich characteristics in their tunable two-dimensional (2d) potentials, energy levels, wave function symmetries, and dipole matrix elements, which are essential to the study of a wide variety of macroscopic quantum phenomena such as tunneling in 2d potential landscapes. |
