Ground state preparation in $(2+1)$-dimensional pure $\mathbb{Z}_2$ lattice gauge theory via deterministic quantum imaginary time evolution

Lento Nagano, Minoru Sekiyama

Deterministic quantum imaginary time evolution prepares the ground state of a 2+1-dimensional Z2 lattice gauge theory with relative error below 0.1 percent up to twelve plaquettes.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

the deterministic QITE can achieve a relative error of less than 0.1% up to a twelve-plaquette system and coupling values in a regime that we study.

C2weakest assumption

The classical tensor-network simulation accurately captures the performance and error scaling of the actual quantum algorithm without introducing artifacts from the classical approximation or truncation.

C3one line summary

Deterministic QITE made gauge-invariant via commuting Pauli operators achieves relative error below 0.1 percent for ground-state preparation in 2+1D Z2 LGT on systems up to twelve plaquettes, as shown by tensor-network simulations benchmarked against DMRG.
