Investigation of low temperature quantum crossover in Josephson junctions
James A. Blackburn, Matteo Cirillo, Niels Grønbech‐Jensen · Journal of Applied Physics · 2017
The evidence for macroscopic quantum tunneling (MQT) in Josephson junctions at low temperatures has been reassessed. Swept bias escape distributions have been modeled with an algorithm-based simulation and the results compared with data from representative published experiments. Signatures expected of a crossover to MQT are not found in the analyzed data.
