Quantum noise scaling in continuously operating multiparameter sensors
Aleksandra Sierant, Diana Méndez-Avalos, Santiago Tabares Giraldo +1
We experimentally investigate the quantum noise mechanisms that limit continuously operating multiparameter quantum sensors. Using a hybrid rf-dc optically pumped magnetometer, we…
Optimal and efficient inference tools for field tracking with precessing spins
Klaudia Dilcher, Piotr Bania, Diana Mendez-Avalos +3
Precise, real-time monitoring of magnetic field evolution is important in applications including magnetic navigation and searches for physics beyond the standard model. One main fi…
Sequential analysis in a continuous spin-noise quantum sensor
Elisabet Roda-Salichs, Giulio Gasbarri, Antoni Alou +5
Many control and detection applications require real-time analysis of signals from sensors, in order to quickly and accurately act upon events revealed by the sensors. Such signal…
Quantum noise in a squeezed-light-enhanced multiparameter quantum sensor
Aleksandra Sierant, Diana Méndez-Avalos, Santiago Tabares Giraldo +1
We study quantum enhancement of sensitivity using squeezed light in a multi-parameter quantum sensor, the hybrid dc-rf optically pumped magnetometer (hOPM) [Phys. Rev. Applied 21,…
Multiparameter quantum sensing and magnetic communications with a hybrid dc and rf optically pumped magnetometer
Michał Lipka, Aleksandra Sierant, Charikleia Troullinou +1
We introduce and demonstrate a hybrid optically pumped magnetometer (HOPM) that simultaneously measures one dc field component and one rf field component quadrature with a single a…
Auto-heterodyne characterization of narrow-band photon pairs
Vindhiya Prakash, Aleksandra Sierant, Morgan W. Mitchell
We describe a technique to measure photon pair joint spectra by detecting the time-correlation beat note when non-degenerate photon pairs interfere at a beamsplitter. The technique…
