Prof. elisa ercolessi (University of Bologna and INFN)13/07/2026, 10:00Invited Talk
The Z3 Schwinger model describes an approximation of one-dimensional quantum electrodynamics, which is able to capture non-perturbative features such as confinement and string breaking. We present the simulation of its quench dynamics on a digital noisy Rydberg atom platform, aiming at the observation of multiple dynamical quantum phase transitions. In order to reach long-time dynamics, we...

Non-perturbative real-time processes such as scattering and false-vacuum decay play a central role in quantum field theory, but remain challenging to simulate classically due to their highly entangled dynamics. We introduce a continuous-variable quantum computing framework for simulating interacting scalar field theories by mapping the spatially discretised theory to a lattice of qumodes. We...

Recent advances in quantum simulations have opened access to the real-time dynamics of lattice gauge theories, providing a new setting to explore how quantum criticality influences thermalization and ergodicity far from equilibrium. Using QuEra's programmable Rydberg atom array, we map out the dynamical phase diagram of the spin-1/2 U(1) quantum link model in one spatial dimension by quenching...

Prof. Masahito Yamazaki (University of Tokyo)13/07/2026, 12:00Invited Talk
We are now at the beginning of the era of utility-scale quantum computers, where quantum devices with a large number of qubits allow us to run circuits that are increasingly challenging to simulate classically. Integrable models will play unique roles in this era, since they (1) provide verifiable results, and (2) can be used to benchmark quantum devices. In this talk, I will discuss both...

Prof. Vlatko Vedral (University of Oxford)13/07/2026, 14:00Invited Talk
I will cover the basic ideas behind how to test quantum effects in the gravitational field in the laboratory. I will then review various approaches to quantum gravity and discuss why the semi-classical ones (in which gravity remains classical) cannot be compatible with the strict formulation of various symmetries (including conservation laws and the equivalence principle). I plan to conclude...

Obtaining the symmetries of a model is a critical step towards developing an understanding and ultimately analytically or numerically solving the model. However, finding symmetries is generally extremely complicated, often being the result of the ingenious thinking of a great mind. In this work, we complement human ingenuity with an algorithm. We leverage the classically efficient Clifford...

While it is generally expected that quantum computing will be much more powerful than digital computing, it is actually non-trivial to identify relevant physics problems which realize quantum advantage. Many people try to find a parameter, called Magic, which would allow to identify such systems. A good candidate is Anti-flatness and a good candidate process is the thermalization of gauge...

Arianna Crippa (ParityQC)14/07/2026, 09:30Invited Talk
This talk presents two studies conducted at ParityQC on HEP applications, covering both theoretical and experimental perspectives. The first study (arXiv:2606.28236) focuses on simulating electromagnetic particle showers in calorimeters, a computationally intensive task due to the complexity of energy deposition distributions. Quantum computing offers a potential alternative, but existing...

Lena Funcke (University of Bonn)14/07/2026, 10:30Invited Talk
Topological terms are notoriously difficult to study with standard Monte Carlo methods due to the sign problem. I review recent progress using sign-problem-free Hamiltonian approaches, including exact diagonalization, tensor networks, and quantum computing, applied to topological terms in (1+1)D, (2+1)D, and (3+1)D lattice gauge theories, both Abelian and non-Abelian. I focus in particular on...

Philipp Hauke (University of Trento)14/07/2026, 11:30Invited Talk
Non-Abelian gauge theories are a main frontier of current quantum simulation with relevance to high-energy physics. In this talk, I will argue why the theories with discrete dihedral gauge symmetries are ideal candidates for near-term devices: These theories fit nicely to the resources available in current qudit quantum hardware such as based on trapped ions. In the recent past, we have spent...

Prof. Alessio Celi (Universitat Autรฒnoma de Barcelona)14/07/2026, 12:00Invited Talk
In this talk, I will first motivate the need for resource-efficient formulations of Hamiltonian lattice gauge theory beyond one spatial dimension. Then, I will introduce the Renormalized Dual Basis (RDB) as a framework that works efficiently for all coupling values in both Abelian and non-Abelian gauge theories. For the Abelian case, I will demonstrate the scalability and superior performance...

Quantum computing for lattice gauge theories (LGT) has drawn rapidly growing interest from a variety of physics communities, which has the potential of overcoming sign problems in Euclidean lattice approach and is suitable for real-time nonperturbative simulation. In this talk, I will review the Kogut-Susskind Hamiltonian for LGT in the electric basis and some studies of performing quantum...

Tomoya Hayata (Keio University)14/07/2026, 14:30
Quantum simulation is a promising approach to studying real-time dynamics in lattice gauge theories, but experimental studies have so far been largely restricted to Abelian models or to one-spatial dimension. In this talk, I will present a quantum simulation of a (2+1)-dimensional non-Abelian lattice gauge theory, that is, a q-deformed $\mathrm{SU(2)}_3$ YangโMills theory on a trapped-ion...

Enrique Rico Ortega (CERN)14/07/2026, 16:00
Understanding confinement and gauge-field dynamics beyond the reach of classical computation is one of the driving motivations for quantum simulation. I will present two complementary advances using superconducting circuits as a platform for lattice gauge theories (LGTs).
First, I will report on a digital quantum simulation of the Z2-Higgs model in (2+1) dimensions on a superconducting...

Johann Ostmeyer (University of Bonn)15/07/2026, 10:00Invited Talk
The state of the art of Suzuki-Trotter and other time evolution methods is reviewed, focussing especially on the progress made over the last few years. A central part of this talk is the estimation of error bounds that has improved greatly within less than a decade. Moreover, a comprehensive overview of generalisations, related methods and alternatives to Trotterization is provided. Depending...

Tensor Networks are a powerful framework for simulating quantum many-body systems while keeping the growth of entanglement under computational control, and as such are a testbed for ideas about how QFT may ultimately be encoded in quantum computers. In this talk, I will describe how Tree Tensor Networks can be adapted to real time Hamiltonian simulation of quantum field theory, with particular...

We present a fully gauge-invariant quantum algorithm for real-time simulations of Quantum Electrodynamics in 2+1 and 3+1 dimensions. Gauge symmetry is preserved exactly through lattice discretisation, digitisation, and qubitisation, ensuring that Gauss's law is automatically satisfied throughout the evolution. Using efficient finite-dimensional representations of bosonic gauge fields, we...

In extreme astrophysical environments like supernova explosions, the large neutrino density can lead to collective flavor oscillations driven by neutrino-neutrino interactions. These phenomena are important to describe flavor transport and have potentially important consequences for both the explosion mechanism and nucleosynthesis in the ejected material. Even simple models of...

In ultradense neutrino gases, which exist for instance in supernovae and in the early Universe, the flavour states of different neutrinos might become entangled. This would render classical simulations of these systems, which are already extremely challenging as is, unfeasible. In this talk, we discuss the conditions under which quantum entanglement may become phenomenologically relevant, and...

Quantum states generated from random tensor networks have been the subject of intense interest across a broad range of fields. In high-energy physics, random tensor networks constitute a tractable toy model of holographic dualities [Hayden et al 2016, Vasseur et al 2019]. In the theory of quantum computing, they describe the states generated by random quantum circuits, which have emerged...

Gauge theory, quantum error correction, and homology theory share a common mathematical backbone that, when made explicit, becomes a practical toolkit for fault-tolerant quantum computation. A CSS code is naturally a length-2 chain complex in which the $X$-stabilizers act as Gauss-law generators and the code space is the gauge-invariant subspace, the toric code being the prototypical...
