Bridging the Terahertz gap for chaotic sources with superconducting junctions
D. R. Gulevich, V. P. Koshelets, F. V. Kusmartsev
We observe a broadband chaotic signal of Terahertz frequency emitted from a superconducting junction. The generated radiation has a wide spectrum reaching 0.7 THz and power suffici…
Josephson Vortex Qubit based on a Confocal Annular Josephson Junction
Roberto Monaco, Jesper Mygind, Valery P. Koshelets
We report theoretical and experimental work on the development of a Josephson vortex qubit based on a confocal annular Josephson tunnel junction (CAJTJ). The key ingredient of this…
Josephson Flux Flow Oscillator: the Microscopic Tunneling Approach
D. R. Gulevich, V. P. Koshelets, F. V. Kusmartsev
We elaborate a theoretical description of large Josephson junctions which is based on the Werthamer's microscopic tunneling theory. The model naturally incorporates coupling of ele…
