Scaling of self-stimulated spin echoes

Sebastian de Graaf, Aditya Jayaraman, Sergey Kubatkin +2

Self-stimulated echoes have recently been reported in the high cooperativity and inhomogeneous coupling regime of spin ensembles with superconducting resonators. In this work, we s…

Quantum bath suppression in a superconducting circuit by immersion cooling

M. Lucas, A. V. Danilov, L. V. Levitin +7

Quantum circuits interact with the environment via several temperature-dependent degrees of freedom. Yet, multiple experiments to-date have shown that most properties of supercondu…

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…
