Understanding conservation of energy during generation of entanglement.
In the experiment for generation of entangled pair of photons via SPDC
Single photons are struck on a BBO crystal.
In about 1 in a trillion of such collisions, two photons emerge.
Questions:
1. Is the combined energy of the two photons exactly equal to the "pump/original" photon?
2. If a photon is the smallest quanta of energy, then how do we explain the fact that its energy has been split among two photons?
or
3. Are there two parts to the energy of a photon? i.e.
a) energy of the photon. i.e. photon as a moving ball of energy.
taking the example of a ball --> the ball can be converted to energy
b) energy on the photon. i.e. momentum of the photon
taking the example of a ball --> the ball is moving at a certain velocity it caries some force/energy/momentum
