Measurement-based simulation of lattice gauge theory dynamics with adaptive quantum circuits on a trapped-ion processor
Hiroki Sukeno, Enrico Rinaldi, Takuya Okuda
Measurement-based quantum simulation (MBQS)---a recently proposed architecture for simulating lattice gauge theories---implements Hamiltonian dynamics by consuming a model-specific…

Fermionic CFTs from topological boundaries in abelian Chern-Simons theories
Kohki Kawabata, Tatsuma Nishioka, Takuya Okuda +1
A quantum field theory is referred to as bosonic (non-spin) if its physical quantities are independent of the spacetime spin structure, and as fermionic (spin) if they depend on it…

Critical behavior of the Schwinger model via gauge-invariant VUMPS
Hirotsugu Fujii, Kohei Fujikura, Yoshio Kikukawa +2
We study the lattice Schwinger model by combining the variational uniform matrix product state (VUMPS) algorithm with a gauge-invariant matrix product ansatz that locally enforces…
