Structured light is attracting significant attention for its diverse applications in both classical and quantum optics. The so-called vector vortex beams display peculiar properties in both contexts due to the nontrivial correlations between optical polarization and orbital angular momentum. Here we demonstrate a new, flexible experimental approach to the classification of vortex vector beams. We … Continua a leggere
Photon indistinguishability plays a fundamental role in information processing, with applications such as linear-optical quantum computation and metrology. It is then necessary to develop appropriate tools to quantify the amount of this resource in a multiparticle scenario. Here we report a four-photon experiment in a linear-optical interferometer designed to simultaneously estimate the degree of indistinguishability … Continua a leggere
The European Research Council (ERC), the body of the European Union that finances projects of excellence addressing frontier research activities, awards the QU-BOSS project of Prof. Fabio Sciarrino with an Advanced Grant of 2.9 million euros. After decades of progress in quantum information science, it is widely expected that in the next few years the … Continua a leggere
