Analysis on the von Neumann entropy under the measurement-based feedback control
Kohei Kobayashi
The measurement-based feedback (MBF) control offers several powerful means for preparing the desired target quantum state. Therefore, it is important to investigate fundamental pro…

Analytical evaluation of the effect of deterministic control error on isolated quantum system
Kohei Kobayashi
We investigate the effect of analog control errors which deterministically occurs on isolated quantum dynamics. Quantum information technologies require careful control for prepari…
