Quantum sensors that compute: quantum computational magnetic-field sensing using a superconducting qubit
Purnendu Sen, Mathieu Ouellet, Saeed A. Khan +6
A measurement of a single-qubit quantum sensor reveals at most 1 bit of information about the signal that was sensed. To perform a classification task on the signal, the convention…

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…
