SUMMARY
The discussion centers on the application of Feynman path integrals to entangled photons, specifically addressing whether the amplitude of one photon should include the amplitude of its entangled partner. Participants clarify that for two entangled photons, one must consider them as a single entity in a 6-dimensional configuration space, where each photon contributes to the overall amplitude. The conversation emphasizes that traditional interference patterns do not apply to entangled photons, and the concept of wavefunction collapse is not straightforward in this context. The Hong-Ou-Mandel effect is cited as an example of interference involving indistinguishable entangled photons.
