Congratulations to our Post Doc Simone Notarincola, who won a Global Marie Curie Postdoctoral Fellowship involving the groups of Prof. M. Lukin (Harvard) and Prof. S. Montangero (Padova).
Congratulations to Nora Reinić, who won a 3-year Marie Curie Doctoral fellowship in Padova through the UNIPhD programme.
A group of Master student from Physics of Data just won the 3rd place in the Quantum Coalition Hack hosted by Yale and Stanford. The team composed by Filippo Angelini (from NucPhys), Giulia Campesan, Tommaso Faorlin, Alessandro Marcomini e Samuele Piccinelli partecipated to the challenge proposed by Microsoft, solving different task in increasing difficulty and developing a creative project based on an application of Grover's algorithm to the board game of Mastermind.
We present some recent developments on the development of efficient unconstrained tree tensor networks algorithms and their application to high-dimensional strongly correlated quantum systems. We present their application to the study of the interacting Hofstadter model and of open many-body quantum systems and, in particular, to the computation of the entanglement of formation in conformal field theories, resulting in the generalization of the Calabrese-Cardy formula to open systems. Finally, we present tensor network simulations of 2+1 and 3+1 dimensional lattice gauge theories at zero and finite densities, and of their confinement properties.

From Einstein to Wheeler: Wave-Particle duality of a single photon
Wave-particle duality is a basic concept of quantum physics, first stated by Einstein about light, and developed about material particles by Louis de Broglie. When applied to a single particle, it allows us to illustrate one of the weirdest properties of the quantum world. I will present wave-particle duality based on using a real experiment, based on a single photon source, one of the key devices in the development of quantum technologies.

Tommaso Faorlin (Master student, UniPd) - Quantum random numbers characterization via quantum-inspired machine learning
The generation of good random numbers impacts basic research and applications beyond pure academic interests: random numbers are required for countless applications, such as cryptography and simulations. For most applications, it is of outmost importance to know if a set of numbers is truly random, pseudo-random or contains some residual correlations. Tensor networks are powerful data structures that spring from quantum many-body physics and are now increasingly applied to machine learning applications. This talk plans to present a possible intersection between these two fields, applying quantum-inspired machine learning to random number generation. We aim to perform and characterise novel statistical checks comparing and characterising the statistical quality of different number sets: correlated, pseudo-random, and quantum-random.
John Preskill (Richard P. Feynman Professor of Theoretical Physics, Caltech) - Quantum Computing and Fundamental Physics
This talk has three parts. In part 1, I discuss the current status and near-term prospects for quantum computing and quantum simulation. In part 2, I emphasize the opportunity to advance our understanding of quantum field theory, high energy physics, and nuclear physics using quantum simulation platforms. In part 3, I describe some recent and ongoing work developing classical and quantum algorithms for simulating high-energy scattering in quantum field theory, particularly in one spatial dimension.
Marco Trenti (Master student, UniPd) - CMS FCNC signal recognitions with Tensor Network Machine Learning Methods
One interesting problem in HEP is the analysis of Flavour Changing Neutral Current (FCNC) events as they violates the Standard Model (SM) prediction. These events are infact heavily suppressed in the SM by the GIM mechanism and are predicted only by supersimmetry theories. In this work we develop a Tensor Network Machine Learning Method targeting the efficient recognition of these rare events with respect to a large pool of possible background events. We will see that the hard part of this task lies in the strong unbalancement of the dataset and thus propose different strategies to overcome this issue.
