Experimental Measurement and Theoretical Analysis of Energy Relaxation Rates of an Interacting Two-Qubit System on a D-Wave Quantum Annealer
Yusei Amano, Sorato Suzuki, Hiroki Kuji +3
In D-Wave quantum annealers, various properties of the ground state have been clarified, whereas the correspondence between theory and experiment for energy relaxation rates in mul…
Quantum Error Mitigation Simulates General Non-Hermitian Dynamics
Hiroki Kuji, Suguru Endo, Tetsuro Nikuni +2
While non-Hermitian Hamiltonians enable exotic dynamical phenomena, implementing their nonunitary time evolution on near-term quantum devices remains challenging. We propose a hard…

Variational quantum-neural hybrid imaginary time evolution
Hiroki Kuji, Tetsuro Nikuni, Yuta Shingu
Numerous methodologies have been proposed to implement imaginary-time evolution (ITE) on quantum computers. Among these, variational ITE (VITE) methods for noisy intermediate-scale…
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…
