11. Heavy meson decays as precision tools for new physics: A search for beyond Standard Model signals

Nicola Losacco (Istituto Nazionale di Fisica Nucleare)

During the years several tensions were found between experimental results and Standard Model (SM) predictions, in particular in the flavour sector. Individually, these anomalies are not large enough to disproof SM but all together they are telling us that a theory beyond it is required. In particular, measurements of semileptonic $B$ decays are pointing out a violation of the lepton flavour...

10. Simulation of quantum algorithms and quantum many-body systems

Rosa Lucia Capurso (Università degli Studi di Bari)

The inadequacy of conventional computers in simulating the behavior of many-body quantum systems, due to their limited computational resources, has led to the development of quantum computers, based upon the intrinsic properties of quantum systems themselves. While an ordinary computer operates on classical bits, a quantum computer is built upon qubits, which are two-level quantum systems that...

9. Primordial Graviton Production and Detection Prospects in the Pre-Big Bang Scenario

Eliseo Pavone (Istituto Nazionale di Fisica Nucleare)

17/12/2024, 14:40

I will discuss the interpretation of the NANOGrav signal as a relic stochastic background of primordial gravitons, potentially produced within the framework of string cosmology's pre-big bang scenario. We demonstrate that this interpretation encounters limitations within a minimal version of the scenario; however, it becomes feasible when considering generalized, non-minimal extensions, even...

2. Security of Quantum Key Distribution

Gabriele Staffieri (Università degli studi di Bari "Aldo Moro")

17/12/2024, 15:00

The security of classical cryptosystems is based on the assumption about the impossibility of solving certain mathematical problems, like the factorization of large numbers. Unfortunately the advent of quantum computers represents a serious problematic owing their exponentially higher computational power; this problem is known as “quantum threat”. However quantum mechanics can be as well...
