If particles are emitted simultaneously (or quasi-simultaneously) by the same entity then they are entangled.
Also I refer to entanglement not only to maximally entangled states but more essentially to mixed entanglement and maximally entangled states would only be a special case of many tiny states entangled together.
Can we say the same thing about the quanta "generated" during the Big Bang or did entanglement "break" during the Big Bang ? What about a "gradient" of entanglement from concentrated entanglement to a mixture of extraordinary many entangled "tiny" states ?
Can we think of everything before the Big Bang as being like a huge tensor network (of entanglement) to some degree ? Why not ?
Can we preserve the idea that everything after the Big Bang was still a huge tensor network to some degree ? Why not ?
Also let's think of 2 Helium Atoms A and B. Let's name A1 electron from orbital 1s and A2 electron 2s from A atom. Similarly B1 electron from orbital 1s, B2 as 2s elecron from B atom. Let's entangle A1 with B1, A2 with B2 using 4 entangled photons. Electrons being so entangled they still have the freedom of staying in their orbitals.
Let's take 2 Pb atom and do the same for each electron.
Let's take n Atoms and divide them into M groups and entangle each electrons with their respective counter part in the other group(s).
In the view of not maximally entangled particles, could one argue against to the generalization of the example above ?
What about ER=EPR (replace entanglement with "wormhole" in each of the questions above and create new "questions" with wormholes - charge-less and charged [...]) ?
