Efficient variational quantum circuit structure for correlated topological phases
Rong-Yang Sun, Tomonori Shirakawa, Seiji Yunoki
We propose an efficient circuit structure of variational quantum circuit \textit{Ansätze} used for the variational quantum eigensolver (VQE) algorithm in calculating gapped topolog…
Parametrized quantum circuit for weight-adjustable quantum loop gas
Rong-Yang Sun, Tomonori Shirakawa, Seiji Yunoki
Motivated by the recent success of realizing the topologically ordered ground state of the exactly solvable toric code model by a quantum circuit on the real quantum device [K. J.…
Monte Carlo study of cuprate superconductors in a four-band - model: Role of orbital degrees of freedom
Hiroshi Watanabe, Tomonori Shirakawa, Kazuhiro Seki +4
Understanding the complex phase diagram of cuprate superconductors is a long-standing challenging problem. Recent studies have shown that orbital degrees of freedom, both Cu …
Local multiplet formation around a single vacancy in graphene: an effective Anderson model analysis based on the block-Lanczos DMRG method
Tomonori Shirakawa, Seiji Yunoki
To better understand the electronic structure of a single vacancy in graphene, we study the ground state property of an effective Anderson model, consisting of three dangling $sp^2…
Automatic quantum circuit encoding of a given arbitrary quantum state
Tomonori Shirakawa, Hiroshi Ueda, Seiji Yunoki
We propose a quantum-classical hybrid algorithm to encode a given arbitrarily quantum state onto an optimal quantum circuit with a finite numbe…
Unified description of cuprate superconductors using four-band - model
Hiroshi Watanabe, Tomonori Shirakawa, Kazuhiro Seki +4
In the 35 years since the discovery of cuprate superconductors, we have not yet reached a unified understanding of their properties, including their material dependence of the supe…
