Preparing the Gutzwiller wave function for attractive SU(3) fermions on a quantum computer
Han Xu, Kazuhiro Seki, Seiji Yunoki
We implement the Gutzwiller wave function for attractive SU(3) fermion systems on a quantum computer using a quantum-classical hybrid scheme based on the discrete Hubbard-Stratonov…
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…
Probabilistic imaginary-time evolution in state-vector-based and shot-based simulations and on quantum devices
Satoshi Ejima, Kazuhiro Seki, Benedikt Fauseweh +1
Imaginary-time evolution, an important technique in tensor network and quantum Monte Carlo algorithms on classical computers, has recently been adapted to quantum computing. In thi…
Quantum conditional mutual information as a probe of measurement-induced entanglement phase transitions
Yuichi Otsuka, Kazuhiro Seki, Seiji Yunoki
We propose that the quantum conditional mutual information (QCMI), computed with a suitably chosen partition of the system, serves as a powerful probe for detecting measurement-ind…
Simulating Floquet scrambling circuits on trapped-ion quantum computers
Kazuhiro Seki, Yuta Kikuchi, Tomoya Hayata +1
Complex quantum many-body dynamics spread initially localized quantum information across the entire system. Information scrambling refers to such a process, whose simulation is one…
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…
