Cavity models of non-Abelian gauge theories
Lucia Valor, Jacquelin Luneau, Klaus Liegener +2
In quantum optics and related fields, cavity quantum electrodynamics provides a powerful framework for modeling the low-energy properties of bound charges coupled to electromagneti…
High-Fidelity Entangled States in a Connectivity-Four Fluxonium Quantum Processor
J. Schirk, N. Bruckmoser, S. M. Taubenberger +10
A central challenge in fluxonium-based quantum processors is the extension of the qubit connectivity to two-dimensional lattices compatible with quantum code-error correction. Here…
Implementing Hamiltonian Renormalization Group Flow on Quantum Computers with VAPOR
Federica Fragomeno, Jorden Roberts, Saeed Rastgoo +1
While Hamiltonian Lattice Gauge Theory is gaining traction, today's limited numerical capacity leaves simulations affected by discretization errors. This motivates the implementati…
Enhancing Variational Quantum Eigensolvers for SU(2) Lattice Gauge Theory via Systematic State Preparation
Klaus Liegener, Dominik Mattern, Alexander Korobov +7
Computing the vacuum and energy spectrum in non-Abelian, interacting lattice gauge theories remains an open challenge, in part because approximating the continuum limit requires la…
Spherically Symmetric Gravity on a Graph I: Theoretical Foundations
Klaus Liegener, Saeed Rastgoo, Jorden Roberts
This manuscript is the first in a series of instalments that investigate spherically symmetric solutions within the effective dynamics program of Loop Quantum Gravity. The choice o…
