Quantum blackbody thermometry

Abstract Blackbody radiation sources are calculable that frequently used in radiometry, temperature dissemination, and remote sensing. Despite their ubiquity, blackbody radiometers have a plethora of systematics. We envision new, primary route to measuring using ensembles polarizable quantum systems, such as Rydberg atoms diatomic molecules. Quantum measurements with these exquisite electric field sensors could enable active feedback, improved design, and, ultimately, lower radiometric thermal uncertainties standards. A portable, calibration-free Rydberg-atom physics package also complement variety classical detector thermometers. The successful merger blackbody-based provides fundamental paradigm for physics.
