Unbiased Hamiltonian Simulation by Reversing Trotter Error Dynamics
Keisuke Murota, Yuta Kikuchi, Enrico Rinaldi +3
Owing to their simplicity and low overhead, Suzuki-Trotter formulas remain the de facto Hamiltonian simulation methods on current quantum computing platforms. Systematic Trotter er…
Dissipative ground-state preparation of a quantum spin chain on a trapped-ion quantum computer
Kazuhiro Seki, Yuta Kikuchi, Tomoya Hayata +1
We demonstrate a dissipative protocol for ground-state preparation of a quantum spin chain on a trapped-ion quantum computer. As a first step, we derive a Kraus representation of a…
Continuous-time evolution via probabilistic angle interpolation and its applications
Tomoya Hayata, Yuta Kikuchi
We explore the applicability of a stochastic time-evolution algorithm based on probabilistic angle interpolation. To simplify the pre-processing of the algorithm, we take the conti…
Onset of thermalization of q-deformed SU(2) Yang-Mills theory on a trapped-ion quantum computer
Tomoya Hayata, Yoshimasa Hidaka, Yuta Kikuchi
Nonequilibrium dynamics of quantum many-body systems is one of the main targets of quantum simulations. This focus - together with rapid advances in quantum-computing hardware - ha…
Simulating sparse SYK model with a randomized algorithm on a trapped-ion quantum computer
Etienne Granet, Yuta Kikuchi, Henrik Dreyer +1
The Sachdev-Ye-Kitaev (SYK) model describes a strongly correlated quantum system that shows a strong signature of quantum chaos. Due to its chaotic nature, the simulation of real-t…
Simulating Floquet scrambling circuits on trapped-ion quantum computers
Kazuhiro Seki, Yuta Kikuchi, Tomoya Hayata +1
Complex quantum many-body dynamics spread initially localized quantum information across the entire system. Information scrambling refers to such a process, whose simulation is one…
