描述了一种移位寄存器，它采用扩展维的约瑟夫森结中出现的通量量子涡旋作为信息位。涡流的位置可以通过适当设计的电路几何形状以及通过施加电流和磁场来控制和操纵。涡旋位置转换所需的时间可以接近约瑟夫森等离子体振荡的周期（10 ps），而本征能量耗散通常为10- 18 J/位移。
A shift register is described which employs as information bits the flux quantum vortices occurring in Josephson junctions of extended dimensions. The positions of the vortices can be controlled and manipulated by an appropriately designed circuit geometry and by application of currents and magnetic fields. The time required for switching of the position of a vortex can approach the period of the Josephson plasma oscillation (∼10 ps) and the intrinsic energy dissipation is typically ≲ 10-18J/shift.
