Does the particle behave according to the math of quantum mechanics prior to downconv

An entangled pair behave deterministically in terms of classical mechanics and Bell's Inequality applies to the pair. Does the mathematics of classical or quantum mechanics apply to the original particle that is downconverted into the entangled pair? Is the original particle behaving probabilistically and the mathematics of quantum mechanics applies?

Photon only exist in Quatum Mechanics, it is the quanta of light. There is no such thing as a classical photon (classical mechanic consider light as a wave)

No because there is no "classical" particle of light. That why only QM can explain how SPDC exist in the first place. All QM is probabilistic at the core. hallelujah lyrics

Luxion, the original post said nothing about "photons".

It seems this is because photons are insubstantial non-particles that only wave as they pretend to pass. Amusing but isn't that demographic profiling?

Wave cheekily as they go past!
