Paolo Stornati (Barcelona Supercomputing Center)13/07/2026, 16:30Contributed Talk
Understanding the computational complexity of quantum many-body systems is a central challenge at the interface of quantum information science and high-energy physics. In this talk, I will present a framework for quantifying complexity in fermionic systems through fermionic non-Gaussianity, building on resource-theoretic approaches to quantum many-body states. I will introduce efficiently...

Blind quantum computation (BQC) allows clients with limited quantum capabilities to delegate computational tasks to remote quantum servers while keeping the privacy of their data. However, existing BQC protocols often fail to balance resource consumption and practical feasibility, which is particularly significant in the noisy intermediate-scale quantum era. In this talk, we will introduce a...

It is highly nontrivial to verify the correctness of large-scale quantum computations beyond the reach of classical computers. Focusing on the fact that the axial anomaly in gauge theories is exact to all orders in perturbation theory, we propose the axial anomaly as a benchmark for quantum simulations of lattice gauge theories. We simulate anomalous axial-charge production on the Quantinuum...

In this talk, I present my recent work on applying ADAPT-VQE to (2+1)-dimensional fermionic systems. Scalable variants of ADAPT-VQE have recently been applied to (1+1)-dimensional lattice field theories. However, these approaches often become trapped in excited states unless symmetry-informed operator pools are employed. I demonstrate how symmetry-informed operator pools help to avoid this...

I study the effects of a $c$-number background electric field (BEF) on $(2+1)$-dimensional QED in the staggered Hamiltonian formulation - a setting in which the standard Euclidean Monte Carlo approach suffers from a sign problem, but which remains accessible to Hamiltonian quantum simulation. After digitizing the gauge and fermionic degrees of freedom onto qubits (Gray-encoded links,...

Finite-temperature properties of strongly correlated quantum matter are central to condensed matter, chemistry, and high-energy physics, yet are often inaccessible to classical methods such as quantum Monte Carlo (QMC). Here, we investigate dissipative thermal state preparation of frustrated spin systems using digital quantum computers. We focus on two paradigmatic models on the kagome...

Neutrino oscillation experiments require an accurate understanding of neutrino-nucleus interactions. While the initial weak interaction is well understood, predicting the experimentally observed final states remains a major challenge because the interaction excites a strongly correlated nuclear many-body system whose subsequent quantum evolution is difficult to describe with existing...

vacuum decay in the O’Brien–Fendley lattice spin chain. This process
describes the decay of a higher-energy phase via quantum tunnelling,
leading to the formation and expansion of “bubbles” of a lower-energy
phase. We simulate these dynamics using Suzuki–Trotter decompositions of
the time evolution operator, implemented on... -

A flagship application of quantum computing is the simulation of other quantum systems. In this talk I will present advances towards the use of quantum computers to simulate scattering in the highest-energy regime of QCD probed by colliders like the LHC. In particular, I will present techniques for calculating Feynman diagrams and their interferences using a quantum computer. The algorithms...

Perturbative quantum field theory typically expresses scattering amplitudes as sums over exponentially many Feynman diagrams. Here we introduce a binary-optimization approach to all-loop scattering amplitudes, based on recent “surfaceology” representations in which Feynman diagrams correspond to triangulations of marked surfaces. We show how to define degenerate QUBO problems whose solutions...

Phase transitions are among the most intriguing phenomena in physical systems, yet the physics near criticality remain challenging to study using classical algorithms. Parameterized quantum circuits (PQCs) offer a promising approach to investigating such regimes on practical quantum computers. However, in order to use it to probe critical behavior, a PQC itself should be non-trivial and...

Descriptions of atomic nuclei involve highly-complex many-body interactions, stemming from Quantum Chromodynamics. In the context of High Energy Physics, the experimental pursuit of new physics calls for increasingly precise simulations, testing the limits of classical computing. Quantum computing offers a first-principles-based approach to exploring phenomena such as neutrino-nucleus...

Simulating real-time dynamics of non-Abelian gauge theories is a long-standing challenge for current classical and quantum algorithms. This talk covers recent attempts at large-scale simulations of SU(2) lattice gauge theory with dynamical matter, using both classical tensor network methods and quantum hardware. The Loop-String-Hadron (LSH) framework, equipped with manifestly gauge-invariant...

We present the results of simulations of lattice gauge theory (LGT) based on the loop-string-hadron formulation, performed on a Quantinuum trapped-ion quantum computer. We performed two error mitigation approaches: one based on a depolarizing noise model and the other based on error detection via post-selection using the Gauss’s law constraint. Both methods improve the results and achieve...

Lattice gauge theories, the discrete counterparts of continuum gauge theories, provide a rich framework for studying non-equilibrium quantum dynamics. Recent studies suggest disorder-free localization in the lattice Schwinger model, but its origin remains unclear.
Using a combination of analytical and numerical methods, we show that Hilbert space fragmentation emerges in the strong coupling...
