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…
Erbium implanted silicon for solid-state quantum technologies
Mark A. Hughes, Naitik A. Panjwani, Matias Urdampilleta +6
Erbium implanted silicon as a quantum technology platform has both telecommunications and integrated circuit (IC) processing compatibility. The electron spin coherence time of Er i…
Coupling of a locally implanted rare-earth ion ensemble to a superconducting micro-resonator
I. Wisby, S. E. de Graaf, R. Gwilliam +5
We demonstrate the coupling of rare-earth ions locally implanted in a substrate (Gd in AlO) to a superconducting NbN lumped-element micro-resonator. The hybrid d…
Evidence for interacting two-level systems from the 1/f noise of a superconducting resonator
J. Burnett, L. Faoro, I. Wisby +9
Here we find the increase in 1/f noise of superconducting resonators at low temperatures to be completely incompatible with the standard tunneling model (STM) of Two Level Systems…
Dynamic parity recovery in a strongly driven Cooper-pair box
S. E. de Graaf, J. Leppäkangas, A. Adamyan +6
We study a superconducting charge qubit coupled to an intensive electromagnetic field and probe changes in the resonance frequency of the formed dressed states. At large driving st…
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…
