Phonon-bottlenecked spin relaxation of Er:CaWO at milliKelvin temperatures

S. Rajendran, B. Mistri, P. K. Sharma +5

We study spin-lattice relaxation times of electron spins in Er:CaWO at millikelvin temperature, detected via their coupling to a low-mode volume superconducting resonato…

In-situ scanning gate imaging of individual two-level material defects in live superconducting quantum circuits

M. Hegedüs, R. Banerjee, A. Hutcheson +6

The low temperature physics of structurally amorphous materials is governed by two-level system defects (TLS), the exact origin and nature of which remain elusive despite decades o…

Loss and decoherence in superconducting circuits on silicon: Insights from electron spin resonance

Aditya Jayaraman, Andrey V. Danilov, Jonas Bylander +1

Solid-state devices used for quantum computation and quantum sensing applications are adversely affected by loss and noise caused by spurious, charged two-level systems (TLS) and s…

Spin echo silencing using a current-biased frequency-tunable resonator

V. Ranjan, Y. Wen, A. K. V. Keyser +5

The ability to control microwave emission from a spin ensemble is a requirement of several quantum memory protocols. Here, we demonstrate such ability by using a resonator whose fr…

Suppression of 1/f noise in solid state quantum devices by surface spin desorption

S. E. de Graaf, L. Faoro, J. Burnett +5

Noise and decoherence due to spurious two-level systems (TLS) located at material interfaces is a long-standing issue in solid state quantum technologies. Efforts to mitigate the e…

Effects of quasiparticle tunneling in a circuit-QED realization of a strongly driven two-level system

J. Leppäkangas, S. E. de Graaf, A. Adamyan +5

We experimentally and theoretically study the frequency shift of a driven cavity coupled to a superconducting charge qubit. In addition to previous studies, we here also consider d…
