Final Report Summary - PERCENT (Percolating Entanglement and Quantum Information Resources through Quantum Networks)
The main scientific goal of PERCENT was the application of quantum information resources in quantum networks for information processing. The project led to novel theoretical results in many different problems, such as new protocols for entanglement distribution in quantum networks, extension of complex networks to the quantum regime, novel methods for quantum computation, new no-go theorem for hidden-variable models, novel protocols for randomness generation and key distribution based on the non-local correlations of entangled states or novel methods for the study of entanglement and quantum correlations based on networks.
Apart from these theoretical results, we also collaborated in a couple of experimental works: a proof-of-principle demonstration of device-independent randomness generation and the experimental demonstration of a dimension witness, a concept that allows for the experimental estimation of the dimension of an unknown quantum system.
Finally, a Proof-of-Concept proposal was submitted and funded within PERCENT for the creation of a new type of random-number generation based on quantum effects. Together with the experimental groups at ICFO led by Prof. Valerio Pruneri and Morgan Mitchell, we implemented a lab demonstration of this proposal attaining a random-numer generation rate of 40 Gbps with a low-cost and simple device.
The project PERCENT has confirmed the initial working vision that quantum networks offer radically new perspectives for quantum information processing, also by establishing new applications that were not anticipated in the original proposal.
