Digital Quantum Simulation of a (1+1)D SU(2) Lattice Gauge Theory with Ion Qudits [PDF]

PRX Quantum
We present a quantum simulation strategy for a (1+1)-dimensional SU(2) non-Abelian lattice gauge theory with dynamical matter, a hardcore-gluon Hamiltonian Yang-Mills, tailored to a six-level trapped-ion-qudit quantum processor, as recently ...

A Gentle Introduction to Lattice Field Theory

Entropy
The principles of Lattice Field Theory (LFT), in particular Lattice Gauge Theory (LGT), are explained for a nonspecialist audience. We describe some of the successes of the program; we also discuss the relationship between LFT and Quantum Cellular ...

Strategies for quantum-optimized construction of interpolating operators in classical simulations of lattice quantum field theories [PDF]

Physical Review D, 2022
It has recently been argued that noisy intermediate-scale quantum computers may be used to optimize interpolating operator constructions for lattice quantum field theory (LQFT) calculations on classical computers.

Diffusion models as stochastic quantization in lattice field theory [PDF]

Journal of High Energy Physics, 2023
In this work, we establish a direct connection between generative diffusion models (DMs) and stochastic quantization (SQ). The DM is realized by approximating the reversal of a stochastic process dictated by the Langevin equation, generating samples from

Krylov complexity in quantum field theory, and beyond [PDF]

Journal of High Energy Physics, 2022
We study Krylov complexity in various models of quantum field theory: free massive bosons and fermions on flat space and on spheres, holographic models, and lattice models with a UV-cutoff.

Entanglement Hamiltonians: From Field Theory to Lattice Models and Experiments [PDF]

Annals of Physics, 2022
Results about entanglement (or modular) Hamiltonians of quantum many‐body systems in field theory and statistical mechanics models, and recent applications in the context of quantum information and quantum simulation, are reviewed.

Implementing the three-particle quantization condition for π + π + K + and related systems

Journal of High Energy Physics, 2022
Recently, the formalism needed to relate the finite-volume spectrum of systems of nondegenerate spinless particles has been derived. In this work we discuss a range of issues that arise when implementing this formalism in practice, provide further ...

Accelerating Lattice Quantum Field Theory Calculations via Interpolator Optimization Using Noisy Intermediate-Scale Quantum Computing. [PDF]

Physical Review Letters, 2019
The only known way to study quantum field theories in nonperturbative regimes is using numerical calculations regulated on discrete space-time lattices.
