Quantum Metrology Protected by Hilbert Space Fragmentation
Atsuki Yoshinaga, Yuichiro Matsuzaki, Ryusuke Hamazaki
We propose an entanglement-enhanced sensing scheme that is robust against spatially inhomogeneous always-on Ising interactions. Our strategy is to tailor coherent quantum dynamics…

Entanglement-enhanced sensing using a chain of qubits with always-on nearest-neighbor interactions
Atsuki Yoshinaga, Mamiko Tatsuta, Yuichiro Matsuzaki
Quantum metrology is the use of genuinely quantum properties such as entanglement as a resource to outperform classical sensing strategies. Typically, entanglement is created by im…

Ballistic propagation of a local impact in the one-dimensional model
Atsuki Yoshinaga
Light-cone-like propagation of information is a universal phenomenon of nonequilibrium dynamics of integrable spin systems. In this paper, we investigate propagation of a local imp…
