Proposed rapid detection of nuclear spins with entanglement-enhanced sensors
Hideaki Hakoshima, Yuichiro Matsuzaki, Toyofumi Ishikawa
Recently, there have been significant developments to detect nuclear spins with an nitrogen vacancy (NV) center in diamond. However, due to the nature of the short range dipole-dip…
Quantum sensing to suppress systematic errors with measurements in the Zeno regime
Alisa Shimada, Hideaki Hakoshima, Suguru Endo +2
Quantum magnetic field sensing is an important technology for material science and biology. Although experimental imperfections affect the sensitivity, repetitions of the measureme…
Possibility of the total thermodynamic entropy production rate of a finite-sized isolated quantum system to be negative for the Gorini-Kossakowski-Sudarshan-Lindblad-type Markovian dynamics of its subsystem
Takaaki Aoki, Yuichiro Matsuzaki, Hideaki Hakoshima
We investigate a total thermodynamic entropy production rate of an isolated quantum system. In particular, we consider a quantum model of coupled harmonic oscillators in a star con…
Relationship between costs for quantum error mitigation and non-Markovian measures
Hideaki Hakoshima, Yuichiro Matsuzaki, Suguru Endo
Quantum error mitigation (QEM) has been proposed as an alternative method of quantum error correction to compensate errors in quantum systems without qubit overhead. While Markovia…
Direct estimation of the energy gap between the ground state and excited state with quantum annealing
Yuichiro Matsuzaki, Hideaki Hakoshima, Kenji Sugisaki +2
Quantum chemistry is one of the important applications of quantum information technology. Especially, an estimation of the energy gap between a ground state and excited state of a…
Multiparameter quantum estimation under dephasing noise
Le Bin Ho, Hideaki Hakoshima, Yuichiro Matsuzaki +2
Simultaneous quantum estimation of multiple parameters has recently become essential in quantum metrology. Although the ultimate sensitivity of a multiparameter quantum estimation…
