Researchers have developed an in situ calibration protocol that simultaneously estimates beam splitter transmissivity and detector quantum efficiency, achieving a five-fold reduction in parameter uncertainty without requiring external procedures. This advancement directly addresses the trade-off between accuracy and speed in characterizing non-Gaussian optical states, which are critical for advancing quantum computation and metrology. By leveraging standard measurement data during device operation, this method streamlines the characterization of complex quantum systems essential for scaling quantum technologies.
