Hamiltonian tomography of dissipative systems under limited access: A biomimetic case study
Koji Maruyama, Daniel Burgarth, Akihito Ishizaki +2
The identification of parameters in the Hamiltonian that describes complex many-body quantum systems is generally a very hard task. Recent attention has focused on such problems of…
Estimation of Coupling Constants of a Three-Spin Chain: Case Study of Hamiltonian Tomography with NMR
Elham Hosseini Lapasar, Koji Maruyama, Daniel Burgarth +3
It has been shown that inter-spin interaction strengths in a spins-1/2 chain can be evaluated by accessing one of the edge spins only. We demonstrate this experimentally for the si…
Maxwell's Demon and Data Compression
Akio Hosoya, Koji Maruyama, Yutaka Shikano
In an asymmetric Szilard engine model of Maxwell's demon, we show the equivalence between information theoretical and thermodynamic entropies when the demon erases information opti…
