Canonical Partition Function on a Quantum Computer through Trotter Interpolation
Taozhi Guo, Gumaro Rendon, Rutuja Kshirsagar
In this work, we present a Gibbs state observable estimation algorithm based on Trotter interpolation, which reaches a state-of-the-art quantum computational cost of $ \tilde{O}(β\…
Discrete time crystals detected by time-translation twist
Ryota Nakai, Taozhi Guo, Shinsei Ryu
We introduce a boundary condition twisted by time translation as a novel probe to characterize dynamical phases in periodically driven (Floquet) quantum systems. Inspired by twiste…
Twisted-Boundary-Condition Formalism for Thermal Transport and an Application to the One-Dimensional XY Spin Chain
Ryota Nakai, Taozhi Guo, Shinsei Ryu
We introduce and formulate the boundary condition twisted by the energy (time translation) in one-dimensional quantum many-body systems. The stiffness against this boundary conditi…
Spatial deformation of many-body quantum chaotic systems and quantum information scrambling
Kanato Goto, Taozhi Guo, Tomoki Nosaka +3
We study the effect of spatial inhomogeneity on quantum information scrambling, a process of spreading and locally hiding quantum information in quantum many-body systems. As a par…
