Seminar talk - Franz Luef
2025-05-20 14:00 - 15:00 (Europe/Rome) | Aula Consulenze, Corso Duca degli Abruzzi 24, Torino, 10129
On May 20, 2025, at 2 PM in Aula Consulenze DISMA, we will have the pleasure of hosting a talk by
Franz Luef (NTNU)
who is visiting Torino for an extended period. He will present a seminar titled
Quantum Time-Frequency Analysis and Quantum Channels.
Abstract. We discuss an extension of time-frequency analysis of signals to operators, most notably density operators, based on a Schroedinger representation of phase space on the Hilbert-Schmidt operators. This leads one naturally to introduce analogs of the short-time Fourier transform and Cohen class representations for operators, etc.
These notions allow one to describe class of operators in terms of Gabor-type frames adapted to this setting. We indicate how this framework provides one with a natural description of quantum channels which is a double-phase space analog of the Gabor matrix of an operator, a useful tool in the study of pseudodifferential operators.
This talk is based on joint and ongoing work with Henry McNulty (Cognite AS, Oslo) and Thomas Strohmer (UC Davis).

QuanTO - Roberto Longo
2025-09-12 00:00 - 23:59
We are very happy to announce the next QuanTO Lecture! This joint initiative is the result of the scientific cooperation among researchers from the Departments of Physics and Mathematics of Politecnico di Torino (DISMA-DISAT) and Università di Torino.
The forthcoming event of this series will take place on September 12th, 2025. We are pleased to host Professor Roberto Longo from the University of Rome Tor Vergata on this occasion, who will talk about the
von Neumann algebras and entropy/energy inequalities in QFT.
Schedule and further details can be found in the website of the series. No registration is required, participation of young students and researchers is especially welcome. Join us and spread the word!

Popularization at UNIGHT
2025-09-27 11:00 - 12:00 | Castello del Valentino, Viale Mattioli 39, Torino, Italy
UNIGHT (Notte Europea delle Ricercatrici e dei Ricercatori) is an annual research popularization event taking place in many European cities. We will celebrate this recurrence in Torino on September 26-27 with several activities.
Riccardo Adami, Lorenzo Romano and Ivan Trapasso are involved in the game-talk
Qubit chiavi in mano: crittografia quantistica per tutti
Can we exchange secrets that no one can intercept? Through an interactive game and simple explanations, we will discover together how physics can make our digital communications unbreakable, today and in the future.
Come and join us on September 27 at Area Talk T2 (Corte del Castello del Valentino, Viale Mattioli 39) from 11.00 to 12.00!

Special lecture by Gianluca Introzzi
2025-11-17 13:00 - 14:30 | Aula 8D, Corso Duca degli Abruzzi 24, Torino, 10129, Italy
Invited lecture by Professor Gianluca Introzzi (University of Pavia).
Title: Incertezza e indeterminazione.
Abstract: Vengono mostrate le profonde differenze tra incertezza classica e indeterminazione quantistica. L’indeterminazione di Heisenberg non è considerata come un principio della meccanica quantistica, in quanto derivabile dai suoi postulati. S’introducono sia l’indeterminazione intrinseca (dovuta alla manifestazione del carattere ondulatorio delle particelle quantistiche), sia quella operazionale (legata a processi di misura di grandezze incompatibili, misurate in rapida successione).
L’indeterminazione intrinseca E-t (energia/tempo) viene proposta con un approccio, dovuto a Niels Bohr, speculare a quello dell’indeterminazione intrinseca X-P (posizione/quantità di moto). Sono introdotte le indeterminazioni universali di Ozawa e di Fujikawa. Infine, viene delineata la contrapposizione tra Ozawa e il gruppo BLW sull’esistenza o meno di un’indeterminazione universale, e sul significato dell’indeterminazione operazionale di Heisenberg.

Title: Certified quantum randomness from Bell inequality violation.
Abstract: In this lecture, the main characteristic features of Quantum Random Number Generators (QRNGs) will be presented. In particular, the entropy-certification protocol for a QRNG based on the violation of the CHSH Bell inequality will be described in detail.
