Giovedì 25 marzo 2021 alle ore 19.00, nell’ambito della manifestazione INgegneria INcontra, Fabio Sciarrino ha tenuto il seminario “La seconda rivoluzione quantistica: dal computer alle comunicazioni”. Le tecnologie quantistiche promettono di migliorare la nostra società in diversi ambiti – quali la crittografia, la simulazione di reazioni chimiche, l’ingegneria dei materiali e le nanotecnologie. Stiamo assistendo ad … Continua a leggere

Today, 14th of April, a new initiative from quantum scientists around the world has been launched:  the “World quantum day”.  The first global celebration will take place in one year, on the 14th of April 2022. The aim of this recurrence is to raise interest in quantum science’s achievements and allow a general audience to … Continua a leggere

Quantum coherence marks a deviation from classical physics, and has been studied as a resource for metrology and quantum computation. Finding reliable and effective methods for assessing its presence is then highly desirable. Coherence witnesses rely on measuring observables whose outcomes can guarantee that a state is not diagonal in a known reference basis. Here, … Continua a leggere

The generation and control of quantum correlations in high-dimensional systems is a major challenge in the present landscape of quantum technologies. Achieving such non-classical high-dimensional resources will potentially unlock enhanced capabilities for quantum cryptography, communication and computation. We propose a protocol that is able to attain entangled states of d-dimensional systems through a quantum-walk-based  transfer … Continua a leggere

Today, 11th of February 2021, the world celebrates the sixth edition of the International Day of Women and Girls in Science, established by the United Nations General Assembly in 2015. Its aim is to increase awareness of the critical role of women within the scientific community and to promote their full and equal access to … Continua a leggere

The Quantum Lab has just published in the journal Science Bulletin a News and Views paper on the recent quantum computational advantage demonstration reported in Science from Prof. Jian-Wei Pan’s team in China. Here is reference to the Science paper https://science.sciencemag.org/content/early/2020/12/02/science.abe8770 News and Views on Science Bulletin F. Sciarrino, N.

Optical interrogation of tissues is broadly considered in biomedical applications. Nevertheless, light scattering by tissue limits the resolution and accuracy achieved when investigating sub-surface tissue features. Light carrying optical angular momentum or complex polarization profiles, offers different propagation characteristics through scattering media compared to light with unstructured beam profiles. Here we discuss the behaviour of … Continua a leggere

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

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
