Adaptive Spectroscopy of Fast Two-Level-System Dynamics in Superconducting Qubits
Fabrizio Berritta, David Pahl, Lukas Pahl +15
Parasitic two-level-system (TLS) defects are a major source of energy relaxation and temporal instability in superconducting quantum processors. Our sub-second adaptive spectroscop…

Enhanced Sensitivity near a Quantum Exceptional Point in the Absence of Engineered Dissipation
Réouven Assouly, Harry Hanlim Kang, Aziza Almanakly +8
Non-Hermitian systems exhibit phenomena absent from Hermitian systems, including exceptional points (EPs), at which two or more eigenvectors coalesce. Conventional implementations…

Driven-dissipative entanglement of distant giant atoms
Aziza Almanakly, Ariadna Soro, Alejandro Vivas-Viaña +15
Quantum interconnects distribute entanglement via controlled light-matter interactions for quantum computing and sensing applications. Many entanglement generation schemes use cohe…
