I searched for entangled matter in cosmological context but didn't find anything that actually answers my question.
Big bang nucleosynthesis is actually a series of chain reactions that produces a certain percentage of the first light elements. Protons, electrons and photons however, based on the interactions that created them in the first place can have a degree of entanglement. Constant matter-antimatter anhilation as well as other processes in the first moments after BB should also have produced entangled matter in the sense if a particle decays and has a quantum property P, if this property is conserved then the resulting particles summation of this property should remain constant.
Any research that is relevant here? Thank you.
