Accelerated characterization of two-level systems in superconducting qubits via machine learning
Avinash Pathapati, Olli Mansikkamäki, Alexander Tyner +1
We introduce a data-driven approach for extracting two-level system (TLS) parameters-frequency , coupling strength , dissipation time , and the pure dephas…

Two-tone spectroscopy for the detection of two-level systems in superconducting qubits
Olli Mansikkamäki, Alexander Tyner, Alexander Bilmes +2
Two-level systems (TLS) of unclear physical origin are a major contributor to decoherence in superconducting qubits. The interactions of individual TLS with a qubit can be detected…
