摘要:
Experimental evidence is presented which shows that quantization of the phase integral is not a necessary condition for the occurrence of quantum interference effects in superconducting weak‐link circuits. Interference patterns observed with weak‐link geometries containing resistive sections differ from their superconducting couterparts only in the effect of Johnson noise which causes a random walk in quantum phase.
