Extracting the photon indistinguishability error from measurable quantum observables

Year: 2025

Type: article

Abstract: We present a method to extract the photon indistinguishability error from Hong–Ou–Mandel interference measurements, accounting for the combined effects of loss and multiphoton noise that contaminate the single-photon Hilbert space. Our analysis resolves apparent inconsistencies in previous interpretations of such measurements. The reported method applies to a wide range of single-photon sources, including quantum dots.
