University of Barcelona Researchers Develop Step Toward Quantum Information Networks

By IQT News posted 11 Nov 2019

(Phys.org) University of Barcelona (UAB) researchers have had to deal with one of the challenges of a quantum information network for the first time: the problem with sorting data from a quantum systems network according to the state in which they were prepared. The researchers have devised an optimal procedure that can identify clusters of identically prepared quantum systems.
The protocol developed by researchers at the UAB shows a natural connection to an archetypical use case of classical machine learning: clustering data samples according to whether they share a common underlying probability distribution.
New Step Toward Quantum Information Networks
This proposal represents a new step towards quantum information networks, since it sets a solid theoretical framework on what is physically possible in the field of automated classification and distribution of quantum information.
