Spectroscopy and Coherent Control of Two-Level System Defect Ensembles Using a Broadband 3D Waveguide
Qianxu Wang, Juan S. Salcedo-Gallo, Salil Bedkihal +4
Defects in solid-state materials play a central role in determining coherence, stability, and performance in quantum technologies. Although narrowband techniques can probe specific…
The Role of Exceptional Points and Transmission Peak Degeneracies in Non-Hermitian Sensing
Alexander S. Carney, Juan S. Salcedo-Gallo, Salil K. Bedkihal +1
Transmission peak degeneracies (TPDs) have emerged as a promising alternative to exceptional points (EPs) for non-Hermitian sensing, providing square-root frequency splitting witho…
Probing the Dynamics of Two-Level System Defect Ensembles via Broadband Cryogenic Transient Dielectric Spectroscopy
Qianxu Wang, Juan S. Salcedo-Gallo, Sara Magdalena Gómez +7
Two-level system (TLS) defects in dielectrics are a major source of decoherence in superconducting circuits, yet their microscopic origin and distribution remain poorly understood.…
Demonstration of a Tunable Non-Hermitian Nonlinear Microwave Dimer
Juan S. Salcedo-Gallo, Michiel Burgelman, Vincent P. Flynn +6
Achieving and controlling non-reciprocity in engineered photonic structures is of fundamental interest in science and engineering. Here, we introduce a tunable, non-Hermitian, nonl…
