HIGHLIGHTS
- who: Haowei Shi from the Published in partnership with The University of New South Wales have published the paper: Ultimate precision limit of noise sensing and dark matter search, in the Journal: (JOURNAL)
- what: Via quantum Fisher information (QFI) calculations, the authors show that entangled source in the form of two-mode squeezed vacuum (TMSV) is optimal for noise sensing in the parameter region of interest. The authors show that the total Fisher information is proportional to the previously well-accepted figure_of_merit-the scan rate (information acquisition rate across all frequencies15,17,19) in homodyne . . .
