GPU-Accelerated Selected Basis Diagonalization with Thrust for SQD-based Algorithms
Jun Doi, Tomonori Shirakawa, Yukio Kawashima +2
Selected Basis Diagonalization (SBD) plays a central role in Sample-based Quantum Diagonalization (SQD), where iterative diagonalization of the Hamiltonian in selected configuratio…
Extending the Handover-Iterative VQE to Challenging Strongly Correlated Systems: and Fe-S Cluster
Pilsun Yoo, Kyungmin Kim, Eyuel E. Elala +10
Accurately describing strongly correlated electronic systems remains a central challenge in quantum chemistry, as electron-electron interactions give rise to complex many-body wave…
Tensor Computing Interface: An Application-Oriented, Lightweight Interface for Portable High-Performance Tensor Network Applications
Rong-Yang Sun, Tomonori Shirakawa, Hidehiko Kohshiro +2
Tensor networks (TNs) are a central computational tool in quantum science and artificial intelligence. However, the lack of unified software interface across tensor-computing frame…
Closed-loop calculations of electronic structure on a quantum processor and a classical supercomputer at full scale
Tomonori Shirakawa, Javier Robledo-Moreno, Toshinari Itoko +18
Quantum computers must operate in concert with classical computers to deliver on the promise of quantum advantage for practical problems. To achieve that, it is important to unders…
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…
Low-energy photoexcitations inside the Mott gap in doped Hubbard and t-J ladders
Sumal Chandra, Kazuya Shinjo, Shigetoshi Sota +2
We investigate changes in the optical conductivity of doped Mott insulators by tuning ultrashort pump pulses to target either the Drude or low-energy absorption regions. Using a ho…
