A photon is a twin spinning vortex more photons effect the local space time ripples some bands are more heavier. The electrons which are smaller single vortex's excite the state of the atom and bounce around these bands from interactions amidst these bands.
this excitation causes the atom to behave more like a probability wave than being anywhere particular.
This activity causes heavy spacetime distribution which causes creasing in space time aligning more than one particle this ceasing aligning allows the 2 excited particles to entangle.
The level of entanglement in a solid is quite high so it's quite stable at room temperature.
If you were to convey data fast across entangled states changing the atom's spin one side is not the optimal approach.
So you send a focused photon down through a possibility of 2 holes it excites an escape route both sides this effect causes the light to exit one hole but behaving like a wave with 1 hole this doesn't happen. So it's not that the particle travels through both holes it's that it waves around 2 optimal routes and interferes with it self due to the creasing caused but it does only go through one of the hole. So it's like you have to lower entanglement zones being both slits and the photon cracks a path down both causing the interference wave.
