A Quantum Hamiltonian Identification Algorithm: Computational Complexity and Error Analysis

Wang, Yuanlong; Dong, Daoyi; Qi, Bo; Zhang, Jun; Petersen, Ian; Yonezawa, Hidehiro


Quantum Hamiltonian identification (QHI) is important for characterizing the dynamics of quantum systems, calibrating quantum devices, and achieving precise quantum control. In this paper, an effective two-step optimization (TSO) QHI algorithm is developed within the framework of quantum process tomography. In the identification method, different probe states are input into quantum systems and the output states are estimated using the quantum state tomography protocol via linear regression...[Show more]
