通过实验研究了约瑟夫森磁通子与长约瑟夫森结中外部磁场感应电势的相互作用。观察了势阱中通量子的热激活，并讨论了探测其预测量子特性的实验。提出了一种设计流子磁双阱势的方法，并建议使用耦合流子态进行量子计算。
The interaction of a Josephson fluxon with an externalmagnetic field-induced potential in a long Josephson junctionis investigated experimentally. The thermal activation of thefluxon from a potential well is observed and experimentsprobing its predicted quantum properties are discussed. Amethod for engineering a magnetic double-well potential for afluxon is proposed and the use of the coupled fluxon statesfor quantum computation is suggested.
