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

DESCRIPTION

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.

Interference From N. Bohr 1949/1983: Discussions with Einstein on Epistemological Problems in Atomic Physics, p. 27 Two possible paths Probability Interference
A heralded single photon source • PPKTP produces HV photon pairs • Detection of a photon in i channel heralds a photon in the s channel • Statistics in s channel tested by Hanbury Brown – Twiss interferometry
Results • Multimode theory reproduces conditional g(2) extremely well • Fitting Parameters: • Pair production rate • Detector time resolution E. Boquillon et al. arXiv:0807.1725
