No Hiding Theorem Confirmed !

[CraigS]

Quantum no-hiding theorem experimentally confirmed for first time

According to the no-hiding theorem, if information is missing from one system (which may happen when the system interacts with the environment), then the information is simply residing somewhere else in the Universe; in other words, the missing information cannot be hidden in the correlations between a system and its environment. Physicists Samuel L. Braunstein at the University of York, UK, and Arun K. Pati of the Harish-Chandra Research Institute, India, first proved the no-hiding theorem in 2007. Until now, however, the no-hiding theorem has been a purely theoretical concept.
…
Now for the first time, a team of physicists consisting of Pati, along with Jharana Rani Samal (deceased) and Anil Kumar of the Indian Institute of Science in Bangalore, India, has experimentally tested and confirmed the no-hiding theorem.

and so .. now the applications …

In the future, the physicists plan to test the no-hiding theorem in more complex situations, such as in the context of coherent quantum teleportation, which will require the control and manipulation of a larger number of qubits. Overall, the quantum no-hiding theorem could have applications in areas such as quantum communication through private quantum channels, as well as black hole evaporation.

So, yet another prediction of Quantum Theory which has passed empirical testing with flying colours !

The Holographic Principle looks to have gained some more credibility with this one, also.

Great stuff !

Most interesting.
What exactly is the information that was lost (bleached) then reconstructed?

G'Day Rob;

A qubit is the quantum equivalent of a bit in binary logic.

Its dimensions are quantum properties of a physical particle.

So, I'd guess it might be something like photon polarisation, or spin (in electrons or nucelii) ??

Sorry men thats way over my head.

Cheers Kev.
