Open DIET 2025

less than 1 minute read

Published:

Acoording to tradition, also this year we are hosting the Open DIET event where highschool students can join for one day the research teams in our Department in innovative projects and see with their own eyes cutting edge technologies and curren trends in modern electronics, artificial intelligence and quantum computing. This year I will propose a (hopefully fun) project where a student can simulate Classical and Quantum Walks with an Arduino-Based LED System. All the details are in this repository. If you happen to be in Rome in that period, let me know!

Attending the 2025 IEEE International Symposium on Circuits and Systems

less than 1 minute read

Published:

I’m going to present a work on Quantum Cryptography at the 2025 IEEE International Symposium on Circuits and Systems (ISCAS 2025). The title of the talk is “Trade-Offs in Cryptosystems by Boolean and Quantum Circuits” where we have analized the security of cryptosystems based on trapdoor permutations against NISQ attacks. The materials will be available soon, and a preliminary schedule is available here.

Joined Qeios

I’ve just joined the Open Sicence Platform Qeios. It is an open-access, open peer review, academic publishing platform. Publishing on Qeios is free and doesn’t rely on editors to accept or reject papers. Instead, reviewers openly evaluate papers after publication, offering feedback to improve the work and guide readers on its quality. This post-publication peer review system allows broad participation, highlighting strong research and limiting the spread of flawed studies, and I believe it to be a kind of alternative to the many flaws current academic publishing has displayed over and over. If you are interested you can check my first contribution on Qeios here.

talks

Azione e costante di Plank

Published:

Talk (in italian) concluding the residential stage in Laboratori Nazionali di Frascati (LNF), supervised by Dott. Danilo Babusci. The topic I studied was the relationship between the quantization of the action functional and the value of Plank’s constant, measured also experimentally during the stage using LEDs. The notes (written in italian) of the talk are available here.

Isometries of the hyperbolic plane and the Möbius group of the sphere

Published:

Talk at the seminar “Geometrie auf der Sphäre und im hyperbolischen Raum” organized by Prof. Margarita Kraus at the Johannes Gutenberg University of Mainz (Germany). The main point was to show that the isometry group of the hyperbolic space is isomorphic to a subgroup of the Möbius group of the sphere. The notes of the talk are available here.

The Hill Equation

Published:

Talk at the seminar “Advanced methods of averaging in Ordinary Differential Equations” organized by Prof. Alan Rendall at the Johannes Gutenberg University of Mainz (Germany). The topic I discussed was about the Hill equation. The website of the event is available here. The notes of the talk are available here.

Two examples in time-dependant statistical mechanics

Published:

Talk at the seminar “Stochastische Techniken in mathematischer Modellierung” organized by Prof. Mária Lukácová-Medvidová at the Johannes Gutenberg University of Mainz (Germany). The main topic was time-dependent statistical mechanics. The web page of the seminar is available here. The notes of the talk are available here.
