[General] Can a single indivisible photon interfere?

[François henault]

Dear Chandra,
About interferometric experiments, perhaps you could have a look to my 
paper "Quantum physics and the beam splitter mystery" presented in your 
SPIE conference "The Nature of Light" 2015:

Best Regards,
Francois
