| 英文摘要 |
| In this paper, a hamiltonian identification approach is proposed for quantum systems using quantum ensemble
classification. First, the quantum ensemble classification method is introduced by combining sampling-based learning
control and gradient flow algorithms, which helps discriminate different quantum systems whose hamiltonian parameters
falling in different intervals, respectively. Second, the intervals for the parameters to be identified are estimated via cross
verification to achieve a reliable result. Third, the hamiltonian parameters are identified by successively refining the estimated
intervals. Finally, the effectiveness and practicability of the proposed hamiltonian identification approach is verified
using numerical simulation. |
