Permutationally Invariant Quantum State Tomography for Fermions
Shion Yamashika, Daisuke Yamamoto
Quantum state tomography provides complete information about a quantum state, but its measurement cost generally grows exponentially with system size. In many-particle quantum simu…
Melting of a Bosonic Mott Insulator in Kagome Optical Lattices with Sign-Inverted Hopping
Kazuma Nagao, Daisuke Yamamoto, Seiji Yunoki +1
Using the discrete truncated Wigner approximation (dTWA), we investigate the nonequilibrium dynamics of ultracold bosons confined in optical kagome lattices, focusing on both unfru…
Measuring entanglement without local addressing in quantum many-body simulators via spiral quantum state tomography
Giacomo Marmorini, Takeshi Fukuhara, Daisuke Yamamoto
Quantum state tomography serves as a key tool for identifying quantum states generated in quantum computers and simulators, typically involving local operations on individual parti…
Dynamics of Interacting Bosons on the Sawtooth Lattice with a Flat Band
Ko Gondaira, Nobuo Furukawa, Daisuke Yamamoto
Quantum many-body systems are expected to relax to a thermal state over time, with some exceptions such as systems with atypical eigenstates. In this study, we investigate the effe…
