An introduction to monitored quantum systems and quantum trajectories: spectrum, typicality, and phases
Ryusuke Hamazaki, Ken Mochizuki, Hisanori Oshima +1
Thanks to recent experimental advances in simulating and detecting quantum dynamics with high precision and controllability, our understanding of the physics of monitored quantum s…
Local spreading of stabilizer Rényi entropy in a brickwork random Clifford circuit
Somnath Maity, Ryusuke Hamazaki
Nonstabilizerness, or magic, constitutes a fundamental resource for quantum computation and a crucial ingredient for quantum advantage. Recent progress has substantially advanced t…
Eigenstate Thermalization Hypothesis with projective representation
Soma Onoda, Osamu Fukushima, Ryusuke Hamazaki +1
The Eigenstate Thermalization Hypothesis (ETH) provides a sufficient condition for thermalization of isolated quantum systems. While the standard ETH is formulated in the absence o…
Optimal Work Extraction from Finite-Time Closed Quantum Dynamics
Shoki Sugimoto, Takahiro Sagawa, Ryusuke Hamazaki
Extracting useful work from quantum systems is a fundamental problem in quantum thermodynamics. In scenarios where rapid protocols are desired -- whether due to practical constrain…
Quasiprobability Thermodynamic Uncertainty Relation
Kohei Yoshimura, Ryusuke Hamazaki
We derive a quantum extension of the thermodynamic uncertainty relation where dynamical fluctuations are quantified by the Terletsky-Margenau-Hill quasiprobability, a quantum gener…
Transitions of the Lyapunov spectrum and entanglement entropy in monitored quantum dynamics with homogeneous unitary gates
Ken Mochizuki, Ryusuke Hamazaki
We explore the Lyapunov spectrum and entanglement entropy in systems evolved by quantum measurements and spatially homogeneous unitary gates. In models with temporally random and F…
