By Lorenza Viola (Department of Physics and Astronomy, Dartmouth College, Hanover, USA) Abstract: Accurately characterizing the spectral properties of environmental noise in open quantum systems is both a prerequisite for quantitative modeling and prediction, and a key step toward optimizing control performance for high-fidelity quantum information processing and quantum science applications. I will describe recent theoretical advances in developing quantum control methods for spectral estimation using qubit-based sensors, as well as proof-of-principle experimental validations using trapped-ion and superconducting qubit devices. ---------------------------------- Institut Henri Poincaré, 11 rue Pierre et Marie Curie, 75005 PARIS http://www.ihp.fr/
