Fabio Grazioso

Post-Doc Fellow

[email protected]

Fabio Grazioso received his Master degree (laurea magistrale) in physics in 2004, from University of Naples “Federico II” (Italy), defending an experimental thesis with the title: “Realization of an Optical Parametric Oscillator with poled crystal for an infrared spectroscopic apparatus”. This thesis research project was supervised by prof. Salvatore Solimeno. He then worked for two years as research specialist in the R&D lab of “duepigreco s.r.l.”, developing a prototype for a Quantum Key Distribution cryptographic device. duepigreco s.r.l. was also the sole Italian representative for Italy for the quantum encryption devices of MagiQ inc. (www.magiqtech.com). In 2006 he started his doctorate at the University of Oxford, and he received his DPhil degree in 2011, defending an experimental thesis with the title “Spectroscopy of Single Colour Centres in Ultra-Pure Synthetic Diamonds”, supervised by prof. Jason M. Smith and prof. Pieter Kok. During his doctorate dr. Grazioso has teached as tutor for Mansfield College’s undergraduate students, for the course of “Fourier Series and Partial Differential Equations”. He has then been postdoctoral fellow at École Normale Superiéure de Cachan (France) until 2012, working in the group of prof. Jean-François Roch, and collaborating with dr. Frédéric Grosshans in several research projects: an experimental project on QKD using NV centres in diamond as single photon source; a device-independent theoretical model of Quantum Random Number Generators; a theoretical description of a robust, sifting-less Quantum Key Distribution protocol, with discrete variables and an arbitrary number of states. From 2012 he has worked as postdoctoral fellow at Université de Montréal, in the Laboratoire d’Informatique théorique et quantique (LITQ) of prof. Gilles Brassard, collaborating with him to extend the complexity model for quantum algorithms beyond the query complexity model.
In late 2014 he has started to collaborate as postdoctoral fellow in Roberto Morandotti’s group (UOP), at INRS, working on the quantum properties of the non-linear micro-ring resonator and single photon source recently developed by the group. He has recently been awarded a MITACS Accelerate internship funding.
