Quantum Data Classification

The Quantum internet is an interesting concept, can this mean understanding how information has been derived, and thus its identity and ownership?

Quantum Data Classification Protocol Brings Us Nearer to Future 'Quantum Internet'

Researchers at Spain’s Universitat Autonoma de Barcelona have developed a protocol that sorts and classifies quantum data by the state in which it was prepared, more efficiently than the comparable classical algorithm. The process identifies clusters of identically prepared quantum systems via a natural link to an archetypal form of classical machine learning: clustering data samples based on a common underlying probability distribution. The researchers also compared the performances of classical and quantum protocols, observing the new protocol significantly overtakes classical approaches, especially for large dimensional data. The protocol is envisioned as a step closer to realizing a quantum Internet, as it establishes a concrete theoretical framework on what is physically possible in the automated classification and distribution of quantum data.  ....
