Solutions to the Schrodinger equation are like things that fit inside of an arbitrary potential energy. Water can fit inside of a glass or it can fit inside of a river bed; the fact that the water takes a different shape doesn't mean it's not water for both. The wave function is the same way. By that logic, a quantum entanglement can (or could be) described by a wave function. I postulated that the wave function is really a captured graviton. If so, then the entanglement between two photons is also a graviton. One might suppose that a graviton has gravitional acceleration fields built into it. But if we know that a captured graviton is identically a wave function, then we know that a graviton must have momentum, position and energy states built into it. But in order for a graviton to contribute to a gravity field, there must be momentum states that change over distance.
This is where the idea of centrifuging two entangled photons comes it, to create the momentum states that change over distance (between the photons).
