 Obiettivo del progetto (Objective)

'Quantum communication networks consist of several nodes that are connected by quantum channels. By exchanging quantum particles, the nodes share quantum correlations, also know as entanglement. Essential for the future development of quantum communication is to understand the design of efficient protocols for the distribution of entanglement between arbitrarily distant nodes. The main objective of the present proposal is to construct the theory of entanglement distribution through quantum networks. At present, very little is known about this fundamental problem, namely about which properties of a quantum network are required to be able to establish entanglement over large distances. Very recently, we have proved that the distribution of entanglement through quantum networks defines a new type of critical phenomenon, an entanglement phase transition called entanglement percolation. These surprising effects do not appear in the standard repeater configuration previously considered. Crucial for the construction of these examples is the use of concepts already known in statistical mechanics, such as percolation. Our scope is to go far beyond these proof-of principle examples and derive the general theoretical framework describing entanglement percolation, exploiting the connection between statistical concepts and entanglement theory. The obtained framework will also be applied to other information resources, such as secret bits. Then, the ultimate aim of the project is to provide a global picture of the distribution of quantum information resources over realistic quantum communication networks.'
