We propose an experimental realisation of the protocol for the counterfactual disembodied transport of an unknown qubit -- or what we call counterportation -- where sender and receiver, remarkably, exchange no particles. We employ cavity quantum electrodynamics, estimating resources for beating the classical fidelity limit -- except, unlike teleportation, no pre-shared entanglement nor classical communication are required.
John Rarity, professor of optical communication systems at the University of Bristol, said, "We experience a classical world which is actually built from quantum objects. The proposed experiment can reveal this underlying quantum nature showing that entirely separate quantum particles can be correlated without ever interacting. This correlation at a distance can then be used to transport quantum information (qbits) from one location to another without a particle having to traverse the space, creating what could be called a traversable wormhole."
Plans are now in progress, in collaboration with leading U.K. quantum experts in Bristol, Oxford and York, to physically build this otherworldly-sounding wormhole in the lab.
"The goal in the near future is to physically build such a wormwhole in the lab, which can then be used as a testbed for rival physical theories, even ones of quantum gravity," Hatim added.
Quantum teleportation is another weird thing where the state of one particle is transmitted to another location and another copy is created (the original is released to its fate and is no longer required).

1) Now that is “Gee Wally! That’s sure neato!” news but the armchair QM gears begin to turn and I wonder, “What does it mean to ol’ Schrödinger's cat?”
2) I mean, if you open up a wormhole to get your quantum state information, is that technically collapsing the quantum wave function?
3) And what about using a femtosecond laser to put Zeno’s paradox into effect?
4) And finally, what about us macro blobs out here in the real world? What can it do for us??
Quoting wizard Joshua P. Warren, "Most important is that tiny portal, that wormhole, between your ears, seated in a lump of warm flesh we call the brain. This wormhole-brain is where your entire conscious experience stems from, and it’s key that we take it seriously. The purpose of science is not to give us truth, but to merely provide models that seem consistent with the current level of human experience and observation. That is why the conclusions based on science are constantly changing. As the swamis say, truth is that which never changes. Only the human consciousness possesses the most important element of understanding truth: context."
The Shadow Out of Time indirectly tells of the Great Race of Yith, an extraterrestrial species with the ability to travel through space and time. The Yithians accomplish this by switching bodies with hosts from the intended time and place. The story implies that the effect, when seen from the outside, is similar to spiritual possession. The Yithians' original purpose was to study the history of various times and places, and they have amassed a "library city" that is filled with the past and future history of multiple races, including humans. Ultimately the Yithians use their ability to escape the destruction of their planet in another galaxy by switching bodies with a race of cone-shaped plant beings who lived 150 million years ago on Earth. The cone-shaped entities (subsequently also known as the Great Race of Yith) lived in their vast library city in what would later become Australia's Great Sandy Desert (22°3′14″S 125°0′39″E).[3]
