Traveling without moving: Quantum communication scheme..

A friend send me this. Its quite interesting and I believe if they achieve this because its just a scheme, those who believe in telepathy will claim that Quantum Mechanics proves telepathy:

(Phys.org)—While Einstein considered quantum entanglement as "spooky action at a distance," and those who fully accept entanglement acknowledge it to be counterintuitive, current entanglement-based quantum communication schemes for transferring an unknown quantum state from one place to another require classical transportation of particles between sender and receiver. Now consider this: Recently, scientists in China at Harbin Institute of Technology, Yanbian University and Changchun University demonstrated what is known as a counterfactual approach in which quantum information can be transferred between two distant participants without sending any physical particles between them. The researchers accomplished this by entangling two nonlocal qubits with each other without interaction – meaning that the present scheme can transport an unknown qubit in a nondeterministic manner without prior entanglement sharing or classical communication between the participants. Moreover, the scientists state that their approach provides a new method for creating entanglement that allows two qubits to be entangled without interaction between them.

We demonstrate quantum information can be transferred between two distant participants without any physical particles traveling between them. The key procedure of the counterfactual scheme is to entangle two nonlocal qubits with each other without interaction, so the scheme can also be used to generate nonlocal entanglement counterfactually. We here illustrate the scheme by using flying photon qubits and Rydberg atom qubits assisted by a mesoscopic atomic ensemble. Unlike the typical teleportation, the present scheme can transport an unknown qubit in a nondeterministic manner without prior entanglement sharing or classical communication between the two distant participants.

So far its only a scheme however:

Quote:

In closing, Zhang says that the present scheme provides a new way for nonlocal quantum information processing, so it may lead to a quantum network that does not require physical particle transmission. "We also hope the present scheme can be realized in a physical experiment. On the other hand, the deeper mechanism behind the counterfactual scheme has not been revealed, which may well excite people's interest in the fundamental of quantum mechanics, such as quantum interference and wave-particle duality."

So what do you think about it? I just hope it will not become the argument for telepathy and other paranormal stuff.
