Aside from the fact that it does work, it will be useful to transfer information at least.
Instantaneously between stars and across the galaxy.
But I've also been thinking about quantum process lately within the human brain, and hence the mind, and Genesis.
That God evidently created the universe as a quantum system, the measurement problem, i.e., the outcomes of possibilites, would prima facie seem to undermine predestination.
God seems disappointed and sad with Adam and Eve, then prior to The Flood and yet again with human arrogance stemming from Babel. The suggestion is that God didn't know the outcome of events within the mind of Man at the quantum level until their wave-functions had collapsed in the process of their protagonists having made choices.
Not that I'd like this thread moved over to "Religion", but I personally find it comforting that at least part of God's purpose for creating free will in humanity seems affirmed by quantum theory. Why should he otherwise be occupied with wanting us to do good, if he already knows what the outcome will be.
Of course, if I knew Him, I'd be Him. But it's curious to otherwise ponder the point of creation.
