Tunable compact on-chip superconducting switch
Julia Zotova, Alexander Semenov, Rui Wang +3
We develop a compact four-port superconducting switch with a tunable operating frequency in the range of 4.8 GHz -- 7.3 GHz. Isolation between channel exceeds 20~dB over a bandwidt…
Control and readout of a transmon using a compact superconducting resonator
Julia Zotova, Shtefan Sanduleanu, Gleb Fedorov +3
We demonstrate control and readout of a superconducting artificial atom based on a transmon qubit using a compact lumped-element resonator. The resonator consists of a parallel-pla…
Tunable Microwave Single-photon Source Based on Transmon Qubit with High Efficiency
Yu Zhou, Zhihui Peng, Yuta Horiuchi +2
Single-photon sources are of great interest because they are key elements in different promising applications of quantum technologies. Here we demonstrate a highly efficient tunabl…
Hybrid single-electron turnstiles with thick superconducting electrodes for improved quasiparticle relaxation
J. T. Peltonen, A. Moisio, V. F. Maisi +3
We demonstrate shadow evaporation-based fabrication of high-quality ultrasmall normal metal -- insulator -- superconductor tunnel junctions where the thickness of the superconducti…
Dynamics of coherent and incoherent emission from an artificial atom in a 1D space
A. A. Abdumalikov, O. V. Astafiev, Y. Nakamura +1
We study dynamics of an artificial two-level atom in an open 1D space by measuring evolution of its coherent and incoherent emission. States of the atom -- a superconducting flux q…
Real-time observation of discrete Andreev tunneling events
V. F. Maisi, O. -P. Saira, Yu. A. Pashkin +3
We provide a direct proof of two-electron Andreev transitions in a superconductor - normal metal tunnel junction by detecting them in a real-time electron counting experiment. Our…
