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…
Quantum metrology based on symmetry-protected adiabatic transformation: Imperfection, finite time duration, and dephasing
Takuya Hatomura, Atsuki Yoshinaga, Yuichiro Matsuzaki +1
The aim of quantum metrology is to estimate target parameters as precisely as possible. In this paper, we consider quantum metrology based on symmetry-protected adiabatic transform…
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…
