Computer quantistici: istruzioni per l’usoBenvenuti nell’era della quantum supremacy Incontro con Fabio Sciarrino, modera Leonardo De Cosmo29 ottobre, ore 18:30 Delle tecnologie quantistiche si parla ormai ovunque ma è complicato riuscire a capirne davvero qualcosa. In un dialogo semiserio, un giornalista scientifico e uno dei più autorevoli ricercatori del settore cercheranno di raccontare cosa sono … Continua a leggere

Criteria for nonclassicality in the prepare-and-measure scenario

Quantum communication networks involving the preparation, sharing, and measurement of quantum states are ubiquitous in quantum information. Of particular relevance within this context is to understand under which conditions a given quantum resource can give rise to correlations incompatible with a classical explanation. Here we consider the so-called prepare-and-measure scenario, in which a quantum or … Continua a leggere

Review paper on “Photonic quantum metrology”

Quantum metrology is one of the most promising applications of quantum technologies. The aim of this research field is the estimation of unknown parameters exploiting quantum resources, whose application can lead to enhanced performances with respect to classical strategies. Several physical quantum systems can be employed to develop quantum sensors, and photonic systems represent ideal … Continua a leggere

Experimental device-independent certified randomness generation with an instrumental causal structure

The intrinsic random nature of quantum physics offers novel tools for the generation of random numbers, a central challenge for a plethora of fields. Bell non-local correlations obtained by measurements on entangled states allow for the generation of bit strings whose randomness is guaranteed in a device-independent manner, i.e. without assumptions on the measurement and … Continua a leggere
