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…
Zero forcing, linear and quantum controllability for systems evolving on networks
Daniel Burgarth, Domenico D'Alessandro, Leslie Hogben +2
We study the dynamics of systems on networks from a linear algebraic perspective. The control theoretic concept of controllability describes the set of states that can be reached f…
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…
Dynamical recurrence and the quantum control of coupled oscillators
Marco G. Genoni, A. Serafini, M. S. Kim +1
Controllability -- the possibility of performing any target dynamics by applying a set of available operations -- is a fundamental requirement for the practical use of any physical…
Logic circuits from zero forcing
Daniel Burgarth, Vittorio Giovannetti, Leslie Hogben +2
We design logic circuits based on the notion of zero forcing on graphs; each gate of the circuits is a gadget in which zero forcing is performed. We show that such circuits can eva…
Quantum System Identification
Daniel Burgarth, Kazuya Yuasa
The aim of quantum system identification is to estimate the ingredients inside a black box, in which some quantum-mechanical unitary process takes place, by just looking at its inp…
