Probing many-body localization crossover in quasiperiodic Floquet circuits on a quantum processor
Kazuma Nagao, Tomonori Shirakawa, Rongyang Sun +2
Many-body localization (MBL) provides a mechanism by which interacting quantum systems evade thermalization, leading to persistent memory of initial conditions and slow entanglemen…
Tensor computing application programming interface: An application-oriented, lightweight API for portable high-performance tensor network computations
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 a unified software interface across tensor-computing fra…

A universal quantum computer can simulate diverse quantum systems, with electronic structure for chemistry offering challenging problems for practical use cases around the hundred-…
Unveiling clean two-dimensional discrete time crystals on a digital quantum computer
Kazuya Shinjo, Kazuhiro Seki, Tomonori Shirakawa +2
In periodically driven (Floquet) systems, evolution typically results in an infinite-temperature thermal state due to continuous energy absorption over time. However, before reachi…
Improved real-space parallelizable matrix-product state compression and its application to unitary quantum dynamics simulation
Rong-Yang Sun, Tomonori Shirakawa, Seiji Yunoki
Towards the efficient simulation of near-term quantum devices using tensor network states, we introduce an improved real-space parallelizable matrix-product state (MPS) compression…
