This event was dedicated to the general public from High School. The news on the event has been promoted regularly thorugh different channels, … Continua a leggere
Scaling-up optical quantum technologies requires a combination of highly efficient multi-photon sources and integrated waveguide components. Here, we interface these scalable platforms, demonstrating high-rate three-photon interference with a quantum dot based multi-photon source and a reconfigurable photonic chip on glass. We actively demultiplex the temporal train of single photons obtained from a quantum emitter to … Continua a leggere
Introducing quantum sensors as a solution to real world problems demands reliability and controllability outside of laboratory conditions. Producers and operators ought to be assumed to have limited resources readily available for calibration, and yet, they should be able to trust the devices. Neural networks are almost ubiquitous for similar tasks for classical sensors: here … Continua a leggere
Friday 13th December 2019 at 16:00. Aula Conversi – Ed. Marconi, Sapienza Università di Roma According to quantum theory, the correlations between outcomes of separated experiments violate Bell inequalities (constraints that any local hidden variable model must satisfy). However, these violations are limited. In principle, higher violations could occur. Since these violations have extraordinary technological applications, it is important … Continua a leggere
Quantum technologies comprise an emerging class of devices capable of controlling superposition and entanglement of quantum states of light or matter, to realize fundamental performance advantages over ordinary classical machines. The technology of integrated quantum photonics has enabled the generation, processing and detection of quantum states of light at a steadily increasing scale and level … Continua a leggere
