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…
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…
Symmetry-adapted sample-based quantum diagonalization: Application to lattice model
Kosuke Nogaki, Steffen Backes, Tomonori Shirakawa +2
We present a symmetry-adapted extension of sample-based quantum diagonalization (SQD) that rigorously embeds space-group symmetry into the many-body subspace sampled by quantum har…
Digital quantum simulation of the Su-Schrieffer-Heeger model using a parameterized quantum circuit
Qing Xie, Kazuhiro Seki, Tomonori Shirakawa +1
We perform digital quantum simulations of the noninteracting Su-Schrieffer-Heeger (SSH) model using a parameterized quantum circuit. The circuit comprises two main components: the…
