So in classical human endeavour, the principle of multiple entanglement became rooted in the concept of the quantum computer as records were quickly broken in the number of entangled pairs being obtained.
Laser light, incidentally, is coherent light.
So in our search for human terms of reference, you could say that coherence catalyses entanglement. Or you might not want to, if you're the argumentative kind.
Let's assume (dangerously) that you're not arguing, and that this is interesting. We know, as far as we can know anything, that our relationships with each other are versions of entanglement. Evidence for this is woolly in comparison to the facts found in missions of the quantum mechanical kind, largely because we are large, and our idiosyncracies are obvious in terms of variability and uniqueness. Not so in our observation of quantum particles. All photons look the same to us. But then, they would, one would have thought, and we must bear in mind that from a short altitudinal distance, humans on Earth become invisible.
Why is this important?
That depends on your belief system. But if you believe that we are in a position to gain from a greater understanding of our similarity to the quantum state, then you can assess your relationships from an entangled viewpoint, thereby appreciating the energetic medium of connectivity at work within them. Some say that certain kinds of relationship arise from a soul that was split into two, and came into this lifetime to reconnect and learn lessons. This type of bond may exist, and if it does, would suggest its entanglement has maintained integrity across many versions of itself, that life is indeed an endless stream of oscillations from one existence to the next. So, if we are party to such non-locality, we may effectively be participating in an evolutionary process whereby the evidence from these types of relationship could catalyse a whole new way of thinking in regard to our quantumly-entangled network, not to mention the matter of life after death.
Dark matter, they now say, makes up a large proportion of the Universe, and even our planet may be covered in it.
I laughed a long time ago about dark matter not being in your bedroom.
