Abstract: As commonly understood, the noise spectroscopy problem---characterizing the statistical properties of a noise process affecting a quantum system by measuring its response---is ill-posed. Ad-hoc solutions assume implicit structure which is often never determined. Thus it… read more here.

DOI: 10.1103/physrevapplied.9.034003
Abstract: Spin noise (SN) spectroscopy measurements on delicate semiconductor spin systems, like single InGaAs quantum dots, are currently not limited by optical shot noise but rather by the electronic noise of the detection system. Here, we… read more here.

DOI: 10.1103/physrevb.96.165308
Abstract: We study theoretically the spin-induced and photon-induced fluctuations of optical signals from a singly-charged quantum dot-microcavity structure. We identify the respective contributions of the photon-polariton interactions, in the strong light-matter coupling regime, and of the… read more here.

DOI: 10.1109/jsen.2019.2923699
Abstract: Metal oxide gas sensors have enabled gas and vapor detection with high sensitivity. However, this type of sensor suffer from lack of selectivity. Noise spectroscopy is one of solution to improve the selectivity. In this… read more here.
