Quantum spectroscopy of topological dynamics via a supersymmetric Hamiltonian
Hiroshi Yamauchi, Satoshi Kanno, Yuki Sato +4
Topological data analysis (TDA) characterizes complex dynamics through global invariants, but classical computation becomes prohibitive for high-dimensional data. We reinterpret ti…
Impact of Measurement Noise on Escaping Saddles in Variational Quantum Algorithms
Eriko Kaminishi, Takashi Mori, Michihiko Sugawara +1
Stochastic gradient descent (SGD) is a frequently used optimization technique in classical machine learning and Variational Quantum Eigensolver (VQE). For the implementation of VQE…
Quantum dark solitons in the 1D Bose gas: From single to double dark-solitons
Kayo Kinjo, Eriko Kaminishi, Takashi Mori +3
We study quantum double dark-solitons by constructing corresponding quantum states in the Lieb-Liniger model for the one-dimensional Bose gas. Here we expect that the Gross-Pitaevs…
Recurrence times of the Lieb-Liniger model in the weak and strong coupling regimes
Eriko Kaminishi, Takashi Mori
Quantum systems exhibit recurrence phenomena after equilibration, but it is a difficult task to evaluate the recurrence time of a quantum system because it drastically increases as…
Construction of quantum dark soliton in one-dimensional Bose gas
Eriko Kaminishi, Takashi Mori, Seiji Miyashita
Dark soliton solutions in the one-dimensional classical nonlinear Schrödinger equation has been considered to be related to the yrast states corresponding to the type-II excitation…
Entanglement prethermalization in the Tomonaga-Luttinger model
Eriko Kaminishi, Takashi Mori, Tatsuhiko N Ikeda +1
Prethermalization refers to the relaxation to a quasi-stationary state before reaching thermal equilibrium. Recently, it is found that not only local conserved quantities but also…
