World Quantum Day

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

Publication on New Journal of Physics

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

Propagation of structured light through tissue-mimicking phantoms

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

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
