Robust phase estimation of the ground-state energy without controlled time evolution on a quantum device
Hiroki Kuji, Yuta Shingu, Tetsuro Nikuni +3
Estimating the ground-state energy of Hamiltonians in quantum systems is an important task. In this work, we demonstrate that the ground-state energy can be accurately estimated wi…
Proposal for realizing quantum-spin systems on a two-dimensional square lattice with Dzyaloshinskii-Moriya interaction by Floquet engineering using Rydberg atoms
Hiroki Kuji, Masaya Kunimi, Tetsuro Nikuni
We theoretically propose a method for implementing the Hamiltonian incorporating Heisenberg and Dzyaloshinskii-Moriya (DM) interactions within Rydberg atoms arranged in a two-dimen…
Characterization and generation of a SQL-beating catlike state through repetitive measurements
Mamiko Tatsuta, Yuichiro Matsuzaki, Hiroki Kuji +2
Sensitivity in metrology without entanglement is limited by the standard quantum limit (SQL). Recent studies have found that the Heisenberg-limited scaling, the ultimate sensitivit…
