3+1D -Term on the Lattice from the Hamiltonian Perspective
Angus Kan, Lena Funcke, Stefan Kühn +5
Quantum and tensor network simulations have emerged as prominent sign-problem free approaches to lattice gauge theories. Unlike conventional Markov chain Monte Carlo methods, they…
Adaptive estimation of quantum observables
Ariel Shlosberg, Andrew J. Jena, Priyanka Mukhopadhyay +3
The accurate estimation of quantum observables is a critical task in science. With progress on the hardware, measuring a quantum system will become increasingly demanding, particul…
Simulating gauge theories with variational quantum eigensolvers in superconducting microwave cavities
Jinglei Zhang, Ryan Ferguson, Stefan Kühn +4
Quantum-enhanced computing methods are promising candidates to solve currently intractable problems. We consider here a variational quantum eigensolver (VQE), that delegates costly…
Investigating a (3+1)D Topological -Term in the Hamiltonian Formulation of Lattice Gauge Theories for Quantum and Classical Simulations
Angus Kan, Lena Funcke, Stefan Kühn +5
Quantum technologies offer the prospect to efficiently simulate sign-problem afflicted regimes in lattice field theory, such as the presence of topological terms, chemical potentia…
SU(2) hadrons on a quantum computer
Yasar Atas, Jinglei Zhang, Randy Lewis +3
We realize, for the first time, a non-Abelian gauge theory with both gauge and matter fields on a quantum computer. This enables the observation of hadrons and the calculation of t…
