Accurate and precise characterization of linear optical interferometers

Understand

We combine single- and two-photon interference procedures for characterizing any multi-port linear optical interferometer accurately and precisely.

• Accuracy is achieved by estimating and correcting systematic errors that arise due to spatiotemporal and polarization mode mismatch.
• Enhanced accuracy and precision are attained by fitting experimental coincidence data to curve simulated using measured source spectra.
• We employ bootstrapping statistics to quantify the resultant degree of precision.
