论文摘要
我们建议利用当前可用的隧道铁磁磁磁性约瑟夫森连接处实现混合超导量子。我们表明，铁磁屏障的特征性滞后行为通过磁场脉冲提供了量子频率的替代性和本质上的数字调整。为了说明设备的功能和局限性，我们讨论了与读出的谐振器的耦合以及磁波的效果。设想使用量子标筒作为噪声检测器及其相关性来研究磁性和超导性的微妙相互作用。
We propose to exploit currently available tunnel ferromagnetic Josephson junctions to realize a hybrid superconducting qubit. We show that the characteristic hysteretic behavior of the ferromagnetic barrier provides an alternative and intrinsically digital tuning of the qubit frequency by means of magnetic field pulses. To illustrate functionalities and limitation of the device, we discuss the coupling to a read-out resonator and the effect of magnetic fluctuations. The possibility to use the qubit as a noise detector and its relevance to investigate the subtle interplay of magnetism and superconductivity is envisaged.
