3. Presentation and overview of quantum computation in hadron physics

Felipe J. Llanes-Estrada (Universidad Complutense de Madrid)

18/12/2025, 09:00

I will quickly cover a few highlights of problems where quantum computing can have an impact in hadron physics, and show some illustrative extant calculations.

8. Quantum entanglement negationism

Juan Antonio Aguilar Saavedra (IFT UAM-CSIC)

18/12/2025, 09:20

Two papers 2507.15947 and 2507.15949 have claimed that quantum entanglement cannot be measured at colliders. I will discuss what is locality, what is entanglement, and show how confused the authors are.

2. Quantum algorithms for bosonic Hamiltonians and applications to lattice field theory

Gloria Tejedor Garcia (Stony Brook University)

The strong nuclear force, described by the theory of quantum chromodynamics (QCD), controls the behavior of quarks and gluons—the fundamental constituents of most visible matter. Despite decades of theoretical and experimental progress, many key questions remain unresolved: How do the dynamics of quarks and gluons give rise to emergent structures such as nucleons and nuclei? What is the phase...

1. Quantum Information in Scattering: from production at future colliders to the structure of fundamental interactions

Sokratis Trifinopoulos

This talk outlines how ideas from quantum information (QI) help characterize fundamental interactions in high-energy scattering.
First, I will discuss the QI landscape at future colliders, focusing on the Electron–Ion Collider. With transverse beam polarization, electron–proton scattering can produce controllable spin entanglement and non-stabilizer (“magic”) states, offering a concrete...

10. What is a particle in curved spacetime? Groupoids.

L. Alberto Ibort (Univ. Carlos III Madrid)

18/12/2025, 15:30

A new approach to describe elementary particles in curved space-times will be discussed. Wigner's program is extended by replacing kinematical symmetry groups by its natural generalization to curved space-times: kinematical groupoids. Then, elementary particles are classified according to the irreducible projective representations of the kinematical groupoid of the given space-time. The same...
