Evolution of entanglement entropy in strongly correlated bosons in an optical lattice
Shion Yamashika, Daichi Kagamihara, Ryosuke Yoshii +1
We investigate the time evolution of the second-order Rényi entropy (RE) for bosons in a one-dimensional optical lattice following a sudden quench of the hopping amplitude . Spe…
Rényi entanglement entropy after a quantum quench starting from insulating states in a free boson system
Daichi Kagamihara, Ryui Kaneko, Shion Yamashika +4
We investigate the time-dependent Rényi entanglement entropy after a quantum quench starting from the Mott-insulating and charge-density-wave states in a one-dimensional free boson…
Demon driven by geometric phase
Ryosuke Yoshii, Hisao Hayakawa
We theoretically study the entropy production and the work extracted from a system connected to two reservoirs by periodic modulations of the electrochemical potentials of the rese…
Passive verification protocol for thermal graph states
Kazuki Akimoto, Shunji Tsuchiya, Ryosuke Yoshii +1
Graph states are entangled resource states for universal measurement-based quantum computation. Although matter qubits such as superconducting circuits and trapped ions are promisi…
