Alessio D’Errico

Alessio D’Errico obtained his bachelor’s and master’s degrees in Physics at the University of Napoli, Federico II, specializing in Physics of Matter and Optics. He started a PhD at the same University, under the supervision of Professor Lorenzo Marrucci, coordinator of the SLAM group (physics of Structured Light and Matter). After a brief postdoc in Napoli, Alessio joined the SQO group in September 2019.

His research orbits around the study of structured light for both classical and quantum applications. In the classical regime, Alessio investigated the generation of structured light beams and the free space trajectories of polarization singularities, with studies ranging from the decay of high-order topological singularities to the generation and stability studies of optical knots.  He also developed techniques to analyze the Orbital Angular Momentum spectrum of unknown optical beams, and participated in devising novel liquid crystal devices for spin-orbit coupling, such as g-plates, magic plates and dual-plates.

Among the quantum optics-oriented applications, Alessio is interested in implementing quantum walk processes using spin-orbit coupling devices, and in the use of these platforms to discover novel fundamental phenomena in topological systems.

In recent years, Alessio’s research focused on the use of novel single-photon resolving time stamping cameras for developing efficient characterization techniques of the spatial structure of two-photon states. This research has led to the demonstration of efficient quantum state tomography using bi-photon interferometric or phase-retrieval-based techniques.

Other research topics of interest are the implementation of adaptive optics techniques for Quantum Key Distribution and quantum imaging, quantum metrology and imaging.
