Title: "Quantum Waveform Estimation"

Abstract: Quantum probes can measure magnetic and electric fields with high sensitivity and spatial resolution, enabling the study of physical and biological phenomena at the nanometer scale. In particular, nitrogen-vacancy centers in diamond have recently emerged as promising sensors, measuring the amplitude of constant and oscillating fields, thanks to coherent control techniques. Unfortunately, these techniques are not suitable for measuring time-varying fields with unknown dynamics. In this talk I will present a novel approach to reconstruct the arbitrary profile of time-varying fields using coherent control of quantum sensors to simultaneously extract information about external fields and correct for unwanted noise sources. These results will enable time-resolved sensing with quantum probes at the nanometer scale, with applications to bio-imaging and neuroscience.
