Quantum Phase Diffusion in a Small Underdamped Josephson Junction
H. F. Yu, X. B. Zhu, Z. H. Peng +8
Quantum phase diffusion in a small underdamped Nb/AlO/Nb junction ( 0.4 m) is demonstrated in a wide temperature range of 25-140 mK where macroscopic quantum tunne…
Quantum and classical resonant escapes of a strongly-driven Josephson junction
H. F. Yu, X. B. Zhu, Z. H. Peng +9
The properties of phase escape in a dc SQUID at 25 mK, which is well below quantum-to-classical crossover temperature , in the presence of strong resonant ac driving have b…
