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…
Quantum anomaly for benchmarking quantum computing
Tomoya Hayata, Arata Yamamoto
Given the rapid advances in quantum computing hardware, establishing systematic strategies for verifying the correctness of quantum computations has become increasingly important.…
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…
Phases of the -deformed Yang-Mills theory at large
Tomoya Hayata, Yoshimasa Hidaka, Hiromasa Watanabe
We investigate the -dimensional -deformed Yang-Mills theory in the lattice Hamiltonian formalism, which is characterized by three parameters: the numbe…
Digital quantum simulation of many-body localization crossover in a disordered kicked Ising model
Tomoya Hayata, Kazuhiro Seki, Seiji Yunoki
Simulating nonequilibrium dynamics of quantum many-body systems is one of the most promising applications of quantum computers. However, a faithful digital quantum simulation of th…
