I think there must be a lot to the subject of Quantum mechanics. You asked "How do we benefit from our quantum natures in any given reality we find ourselves?" I have some thoughts about this. At the outset I will be clear that I am a Christian so my remarks are based upon a Christian perspective. Quantum entanglement and non-local effects are the two concepts that are probably most obvious to relate to the spiritual reality recognized in the Bible. Understanding this helps me quite a bit as my faith and hope are increased. I have read that in the former Soviet Union Christians could hold clandestine meetings because those who were really believers knew where and when to gather even if it was not announced due to the risk of infiltration. I believe the Holy Spirit showed the true Christians where to meet. Jesus saw things from a distance supernaturally (John 1:48) I am not any sort of expert but it seems to me that these phenomena are likely related to the concepts of Quantum mechanics such as I mentioned above. I do suppose that a book about Quantum mechanics and the Bible could be written. Instances of what I call "teleportation" are described in a few places in the Bible . I believe that when a person is born again something spiritual and supernatural happens to them. It seems we become "connected" to the Love of God expressed through Jesus. If you look at verb tenses in the Bible you will see that events "outside" of time but having a moment of occurrence in our timeline are described. Jesus is the "Lamb slain before the foundation of the world" and believers are those whom he "foreknew". We "are seated with Him in Heavenly places" (outside of time,again). This is why, I believe, that the "Spirit of Jesus is the Spirit of prophecy" .Because Jesus exists outside of time. He entered our reality but exists outside time as do we, only our wickedness separated us from God. Getting "born again" restored the connection, I think. I hope these rough remarks are useful to you in seeing how quantum mechanics relates to spiritual realities that are really important to how we function here in this reality. The book in the picture is an interesting discussion of Quantum mechanics. I think the theory of everything comes down to a single verse "God is love."
I think we are on the verge of the end of history as we know it. The godly righteous ones will see a transformation of their reality and will be free from the threat of evil forever. The evil ones will be permanently disbarred from the spiritual plane of the righteous. Unfortunately for the devil and his fallen angels and their human collaborators this means the end of anything pleasurable for them and the beginning of endless flames. The demonic entities plaguing us need to harm, consume and control us because they have lost connection with eternal life and the Author of it. The evil are trapped in a cycle of doom. The harder they persecute us, the nearer they bring their own eternal judgement and damnation. It can be fun to watch when you know what you are seeing(Psalm 2). What they intend to harm us and damage is (I am speaking as if you are "saved" ) is making us into beings eternally fit to sit at the right hand of our loving Heavenly Father. If the wicked and their evil spiritual enablers could really lastingly alter our minds and souls to our detriment (again, speaking as if you are "saved") then we would not be accountable for our actions.
