Counterfactual quantum cryptography (CQC) is used here as a tool to assess the status of the quantum state: Is it real/ontic (an objective state of Nature) or epistemic (a state of the observer's knowledge)? In contrast to recent approaches to wave function ontology, that are based on realist models of quantum theory, here we recast the question as a problem of communication between a sender (Bob), who uses interaction-free measurements, and a receiver (Alice), who observes an interference pattern in a Mach-Zehnder set-up. An advantage of our approach is that it allows us to define the concept of "physical", apart from "real". In instances of counterfactual quantum communication, reality is ascribed to the interaction-freely measured wave function (ψ) because Alice deterministically infers Bob's measurement. On the other hand, ψ does not correspond to the physical transmission of a particle because it produced no detection on Bob's apparatus. We therefore conclude that the wave function in this case (and by extension, generally) is real, but not physical. Characteristically for classical phenomena, the reality and physicality of objects are equivalent, whereas for quantum phenomena, the former is strictly weaker. As a concrete application of this idea, the nonphysical reality of the wavefunction is shown to be the basic nonclassical phenomenon that underlies the security of CQC.
Traveling without moving: Quantum communication scheme transfers quantum states without transmitting physical particles
This isn't quantum woo or magic. These are scientist confirming things that ancients, mystics, philosophers and some scientist have been saying for years. Again it isn't magic, it's simply saying, OUR REALITY IS PART OF A WHOLE AND THIS WHOLE MAY CONTAIN ALL THE INFORMATION ABOUT WHAT STATES CAN BE PERCEIVED.
Since there exists in this four dimensional structure [space-time] no longer any sections which represent "now" objectively, the concepts of happening and becoming are indeed not completely suspended, but yet complicated. It appears therefore more natural to think of physical reality as a four dimensional existence, instead of, as hitherto, the evolution of a three dimensional existence.

WHERE DID I ACCUSE SCIENCE????
There could be an infinite or close to infinite number of 3 dimensional nows in 4 dimensional space-time and the 3 dimensional nows give us the illusion of separation from the whole.
Yet another blow to scientific realism.
Nirvana is a state of pure blissful knowledge... It has nothing to do with the individual. The ego or its separation is an illusion. Indeed in a certain sense two "I"'s are identical namely when one disregards all special contents — their Karma. The goal of man is to preserve his Karma and to develop it further... when man dies his Karma lives and creates for itself another carrier.
The multiplicity is only apparent. This is the doctrine of the Upanishads. And not of the Upanishads only. The mystical experience of the union with God regularly leads to this view, unless strong prejudices stand in the way.
We do not belong to this material world that science constructs for us. We are not in it; we are outside. We are only spectators. The reason why we believe that we are in it, that we belong to the picture, is that our bodies are in the picture. Our bodies belong to it. Not only my own body, but those of my friends, also of my dog and cat and horse, and of all the other people and animals. And this is my only means of communicating with them.

So like I said, the mystics, Philosophers and Spiritualist have been right all along. It's amazing that people like Plato and Parmenides could grasp these things without the scientific knowledge we have today.
But not for macroscale objects, so if this is your "Therefore, magic" moment, I hate to break it to you...this sort of thing only applies to very very small scales.

I think it's important to really consider what "physical" even means.
