Pulsed Electron Spin Resonance of an Organic Microcrystal by Dispersive Readout
Ailsa Keyser, Jonathan Burnett, Sergey Kubatkin +4
We establish a testbed system for the development of high-sensitivity Electron Spin Resonance (ESR) techniques for small samples at cryogenic temperatures. Our system consists of a…
Fast tunable high Q-factor superconducting microwave resonators
S. Mahashabde, E. Otto, D. Montemurro +3
We present fast tunable superconducting microwave resonators fabricated from planar NbN on a sapphire substrate. The wavelength resonators are tuning fork shaped and tuned b…
Two-level systems in superconducting quantum devices due to trapped quasiparticles
S. E. de Graaf, L. Faoro, L. B. Ioffe +6
A major issue for the implementation of large scale superconducting quantum circuits is the interaction with interfacial two-level system defects (TLS) that leads to qubit relaxati…
Towards quantum-limited coherent detection of terahertz waves in charge-neutral graphene
S. Lara-Avila, A. Danilov, D. Golubev +7
Spectacular advances in heterodyne astronomy with both the Herschel Space Observatory and Stratospheric Observatory for Far Infrared Astronomy (SOFIA) have been largely due to brea…
Near-Field Scanning Microwave Microscopy in the Single Photon Regime
S. Geaney, D. Cox, T. Hönigl-Decrinis +5
The microwave properties of nano-scale structures are important in a wide variety of applications in quantum technology. Here we describe a low-power cryogenic near-field scanning…
Uniform doping of graphene close to the charge neutrality point by polymer-assisted spontaneous assembly of molecular dopants
Hans He, Kyung Ho Kim, Andrey Danilov +12
Tuning the charge carrier density of two-dimensional (2D) materials by incorporating dopants into the crystal lattice is a challenging task. An attractive alternative is the surfac…
