Non-Abelian String-Breaking Dynamics on a Qudit Quantum Computer
Manuel John, Keshav Pareek, Peter Tirler +7
Gauge theories form the foundation of the Standard Model of particle physics. These theories can exhibit confinement, where charged particles only occur in bound states, connected…
Programmable Fermionic Quantum Processors with Globally Controlled Lattices
Gabriele Calliari, Charles Fromonteil, Francesco Cesa +4
We introduce a framework for realizing universal fermionic quantum processing with globally controlled itinerant fermionic particles. Our approach is tailored to the example of neu…
Imaginary time evolution and ground state preparation using unitary multi-copy protocols
Tal Schwartzman, Torsten V. Zache, Hannes Pichler +1
Efficient low-energy state preparation is a key objective in quantum computation and quantum simulation. Quantum imaginary-time evolution replaces real-time dynamics with imaginary…
Field digitization scaling in a symmetric model
Gabriele Calliari, Robert Ott, Hannes Pichler +1
The simulation of quantum field theories, both classical and quantum, requires regularization of infinitely many degrees of freedom. However, in the context of field digitization (…
Real-time collisions of fractional charges in a trapped-ion Jackiw-Rebbi field theory
Alan Kahan, Pablo Viñas, Torsten V. Zache +1
We propose and analyze a trapped-ion quantum simulator of the Jackiw-Rebbi model, a paradigmatic quantum field theory in (1+1) dimensions where solitonic excitations of a scalar fi…
U(1) lattice gauge theory and string roughening on a triangular Rydberg array
Lisa Bombieri, Torsten V. Zache, Hannes Pichler +1
Lattice gauge theories (LGTs) describe fundamental interactions in particle physics. A central phenomenon in these theories is confinement, which binds quarks and antiquarks into h…
