Epitaxial NbN-junction-based self-shunted superconducting flux qubit with high anharmonicity
Tokunoshin Uchida, Shingo Nozaki, Daiki Kurihara +5
We report a demonstration of a self-shunted superconducting flux qubit (SSFQ) as an ultracompact, strongly anharmonic, and long-lifetime qubit by using the full epitaxially grown N…
Sidewall spacer passivated epitaxial NbN/AlN/NbN Josephson junctions for superconducting qubit applications
Koki Honda, Daiki Kurihara, Hiroki Kutsuma +2
Epitaxial NbN/AlN/NbN Josephson junctions are promising alternatives to conventional Al/AlO/Al junctions for superconducting qubits due to their crystalline tunnel barriers and…
Commissioning the CMB polarization telescope GroundBIRD with the full set of detectors
Miku Tsujii, Jochem J. A. Baselmans, Jihoon Choi +39
GroundBIRD is a ground-based cosmic microwave background (CMB) experiment for observing the polarization pattern imprinted on large angular scales ( ) from the Teide Obse…
Pointing calibration of GroundBIRD telescope using Moon observation data
Y. Sueno, J. J. A. Baselmans, A. H. M. Coppens +16
Understanding telescope pointing (i.e., line of sight) is important for observing the cosmic microwave background (CMB) and astronomical objects. The Moon is a candidate astronomic…
