Synchronisation of cyclic coupled Josephson junctions and its microcontroller-based implementation

[摘要] Based on Routh–Hurwitz criterion, this paper reports on synchronisation of two coupled 3D Josephson junctions via cyclic coupling. Analytical conditions which lead to stable synchronisation through the cyclic coupling were derived. Numerical and microcontroller-based circuit simulations are employed to verify the feasibility and effectiveness of the derived analytical criteria. The cyclic coupling has potential applications in neural information transmission and communication in natural systems.
