The QuantHEP Conferences aim:

• to present and discuss ideas and results on how Quantum Technologies can help address scientific challenges in High-Energy Physics (HEP), and how in turn HEP can bring new insights into Quantum Information Science;
• to bring the QT and HEP communities closer together and foster their scientific collaboration.

The acronym QuantHEP comes from the merging of the names of the sections of the arXiv used by the QT and HEP communities, respectively: Quantum Physics (quant-ph), and High-Energy Physics (hep-ex, hep-lat, hep-ph, hep-th).

The first QuantHEP Conference will take place in Bari, Italy, on 25-27 September 2023.

With the goal of making the QuantHEP Conferences a community-driven annual meeting, a Steering Committee has been established.

To apply to organise the QuantHEP Conference 2024, please submit your proposal by 15 October 2023 to:

The QuantHEP Seminar is an initiative of the research project QuantHEP – Quantum Computing Solutions for High-Energy Physics aiming at:

• presenting and discussing ideas and results on how Quantum Computing – and Quantum Technologies (QT) in general – can help address scientific challenges in High-Energy Physics (HEP), and how in turn HEP can bring new insights into Quantum Information Science;
• bringing the QT and HEP communities closer together and foster their scientific collaboration

A research by the Quantum Theory group of the Department’s Physics and Astronomy of the University of Padua published in «Nature Communication»: a new theoretical approach paves the way for the study of phenomena previously impossible to investigate.

Quantum field theories are of paramount importance in our understanding of the fundamental constituents of matter and their interactions: their study represents a cornerstone of contemporary research, ranging from high-energy particle physics to condensed-matter physics. However, describing their quantum many-body behavior is an extremely challenging task. Despite more than fifty years of developments of numerical and analytical methods to study these systems and numerous great achievements, many fundamental phenomena are still beyond reach of Monte Carlo methods, the most powerful numerical tool used to investigate these systems when no analytical solutions are available.

A paper published on Nature Communication this week by the Quantum Theory group of the Physics and Astronomy department of Padova University, presents a leap forward paving the way to the study of phenomena precluded before, introducing efficient numerical algorithms for investigating lattice gauge theories in the realistic scenario of three spatial dimensions.

The work considers complex mathematical structures, Tensor Networks, and for the first time, generalize them showing that tensor network methods provide a computational efficient description of the lowenergy behavior of quantum field theories in three dimensions, such as quantum electrodynamics. By exploiting sophisticated algorithms they study how electrons and positrons organizes themselves in the different regimes in scenarios precluded before, overcoming the so-called “sign-problem” that curses Monte Carlo methods in some regimes. They observe some intriguing quantum phenomena completely Schematic representation of the electron-positron interaction (left) and three dimensional tensor network structure used to simulate the system (right) 3 counterintuitive in the “classical” world, such as the instability of the vacuum with respect to the spontaneous creation of particles and antiparticles and the peculiar behaviors of the interaction potential between two charges that changes its shape according to the strength of quantum interactions, called “confinement”.

These results show for the first time the potential of tensor network methods to the study of realistic quantum field theories, opening new perspective on the connection between high-energy phenomena and entanglement theory, the latter being at the basis of tensor network methods. These findings could stimulate the application of these strategies to processes of interest in particle physics and challenging open problems that are at the center of theoretical and experimental research efforts, such as the mechanism of quark confinement in the context of the Standard Model.
