Exploring Probability Interference in Photon Measurements: Insights from Bohr and Einstein

This discussion delves into the epistemological problems in atomic physics as debated by Niels Bohr and Albert Einstein. It focuses on the potential paths of probability interference using a heralded single photon source where PPKTP produces HV photon pairs. Detection in one channel confirms the presence of a photon in a second channel. The results, tested using Hanbury Brown-Twiss interferometry, highlight the accuracy of multimode theory in reproducing conditional g(2) statistics. Key parameters include pair production rate and detector time resolution.
