Zhao, and Siyuan Han Quantum phase diffusion in a small underdamped Nb/AlO x /Nb junction ( ∼0.4 μ m 2 ) is demonstrated in a wide temperature range of 25–140 mK where macroscopic quantum tunneling (MQT) is the dominant escape mechanism. We propose a two-step transition model to describe the switching process in which the es... [Phys. Rev. Lett. 107, 067004] Published Wed Aug 03, 2011
