Quasi-B-mode generated by high-frequency gravitational waves and corresponding perturbative photon fluxes
Fangyu Li, Hao Wen, Zhenyun Fang +3
Interaction of very low-frequency primordial(relic) gravitational waves(GWs) to cosmic microwave background(CMB) can generate B-mode polarization. Here, for the first time we point…
Optical responses of the switching currents in Al and Nb Josephson junctions
Yiwen Wang, Pinjia Zhou, Lianfu Wei +5
We experimentally demonstrated the optical responses of the switching currents in two types of Josephson tunnel junctions: Al/AlOx/Al and Nb/AlOx/Nb. The radiation-induced switchin…
Photon-noise limited sensitivity in titanium nitride kinetic inductance detectors
Johannes Hubmayr, Jim Beall, Dan Becker +14
We demonstrate photon-noise limited performance at sub-millimeter wavelengths in feedhorn-coupled, microwave kinetic inductance detectors (MKIDs) made of a TiN/Ti/TiN trilayer supe…
Photon-induced thermal effects in superconducting coplanar waveguide resonators
Yiwen Wang, Pinjia Zhou, Lianfu Wei +6
We experimentally investigated the optical responses of a superconducting niobium resonator. It was found that, with increasing radiation power, the resonance frequency increases m…
Experimental demonstrations of high-Q superconducting coplanar waveguide resonators
Haijie Li, Yiwen Wang, Lianfu Wei +6
We designed and successfully fabricated an absorption-type of superconducting coplanar waveguide (CPW) resonators. The resonators are made from a Niobium film (about 160 nm thick)…
Landau-Zener-Stuckelberg interferometry in multilevel superconducting flux qubit
Xueda Wen, Yiwen Wang, Shanhua Cong +7
Landau-Zener-Stuckelberg interferometry has been extensively investigated in quantum two-level systems, with particular interests on artificial system such as superconducting flux…
