Tom Yager,Arseniy Lartsev,Sumedh Mahashabde,Sophie Charpentier,Dejan Davidovikj,Andrey Danilov,Rositza Yakimova,Vishal Panchal,Vishal Panchal,Olga Kazakova,Alexander Tzalenchuk,Alexander Tzalenchuk,Samuel Lara-Avila,Sergey Kubatkin +13 more
TL;DR: It is shown that inspection with an optical microscope allows surprisingly simple and accurate identification of single and multilayer graphene domains in epitaxial graphene on silicon carbide (SiC/G) and is informative about nanoscopic details of the SiC topography, making it ideal for rapid and noninvasive quality control of as-grown SiC/ G.
Journal ArticleDOI
Two-level systems in superconducting quantum devices due to trapped quasiparticles.
S. E. de Graaf,Lara Faoro,Lara Faoro,Lev Ioffe,Lev Ioffe,Sumedh Mahashabde,Jonathan Burnett,Tobias Lindström,Sergey Kubatkin,Andrey Danilov,A. Ya. Tzalenchuk,A. Ya. Tzalenchuk +11 more
TL;DR: Here, a previously unexplored decoherence mechanism is revealed in the form of a new type of TLS originating from trapped QPs, which can induce qubit relaxation and thus affect coherence over exponentially long time scales.
Journal ArticleDOI
Optical Response of a Cold-Electron Bolometer Array Integrated in a 345-GHz Cross-Slot Antenna
TL;DR: In this article, two series/parallel arrays of ten cold-electron bolometers with superconductor-insulator-normal tunnel junctions were integrated in orthogonal ports of a cross-slot antenna.
Journal ArticleDOI
Fast Tunable High-Q-Factor Superconducting Microwave Resonators
Sumedh Mahashabde,Ernst Otto,Domenico Montemurro,Sebastian de Graaf,Sergey Kubatkin,Andrey Danilov +5 more
TL;DR: In this paper, a fast tunable superconducting microwave resonators fabricated from planar NbN on a sapphire substrate are presented. The 3 lambda/4 wavelength resonators are tuning fork shaped and tuned by passing a dc current that controls the kinetic inductance of the tuning fork prongs.
Journal ArticleDOI
A Frequency Selective Surface Based Focal Plane Receiver for the OLIMPO Balloon-Borne Telescope
Sumedh Mahashabde,Alexander S. Sobolev,Andreas Bengtsson,Daniel Andrén,M. A. Tarasov,Maria Salatino,Paolo de Bernardis,Silvia Masi,Leonid Kuzmin +8 more
TL;DR: In this article, a focal plane array of Cold-Electron Bolometer (CEB) detectors is integrated in a frequency selective surface (FSS) for the 350 GHz detection band of the OLIMPO balloon-borne telescope.
