talk

The collision of elementary and composite particles in gauge theories is a crucial way to unveil their properties. As direct calculation of the scattering dynamics is typically infeasible, we rely on numerical simulation to study collision physics. However, classical methods face severe limitations, such as the sign problem for quantum Monte Carlo and higher spatial dimensionality for tensor...

269. Generative modeling with Gaussian Boson Sampling: classically trainable Bosonic Born Machines

talk

Quantum generative modeling has emerged as a promising application of quantum computers, aiming to model complex probability distributions beyond the reach of classical methods. In practice, however, training such models often requires costly gradient estimation performed directly on the quantum hardware. Crucially, for certain structured quantum circuits, expectation values of local...

326. Quantum Generative Modeling for Multidimensional Loop Feynman Diagram Integration

Konstantinos Pyretzidis (IFIC ( UV-CSIC ))

talk

Perturbative Quantum Field Theory is the central framework for precise predictions of collider observables in high-energy particle physics, where loop Feynman diagrams and final-state phase space require the evaluation of multidimensional integrals. The standard approach, adaptive importance sampling as used in VEGAS, iteratively shapes a proposal probability density over a discretized grid....

323. Physics-Informed Variational Quantum Circuits for QCD Phenomenology

talk

Variational quantum circuits (VQCs) provide a flexible framework for modeling multidimensional functions arising in QCD phenomenology. We present a set of physics-informed VQC architectures tailored to different phenomenological tasks by incorporating problem-specific kinematic information into the circuit design. The proposed approach is illustrated through two case studies: the interpolation...

289. Entanglement in Collective Neutrino Oscillations on a Quantum Computer

Katarina Bleau (Johannes Gutenberg University Mainz)

talk

Simulations on a quantum computer have been propounded as a next-generation tool for studying flavour oscillations in dense neutrino gases, which exist for instance inside supernovae or neutron star mergers. However, the advantage of quantum algorithms over conventional methods hinges on the presence of quantum entanglement in the neutrino ensemble, and it has been argued that such...

266. Neutrino thermalization via randomization on a quantum processor

talk

The dynamical evolution of neutrino flavor in supernovae can be modeled by an all-to-all spin Hamiltonian with random couplings. Simulating such two-local Hamiltonian dynamics remains a major challenge, as methods with controllable accuracy require circuit depths that increase at least linearly with system size, thereby exceeding the capabilities of current quantum devices. The eigenstate...
