An improvement of D-MORPH method for finding quantum optimal control

Abstract

The paper examines the prominent algorithm D-MORPH to search for the optimal control of a quantum system in order to implement desired unitary evolution of the quantum system at the final time, and reveals new mathematical expressions for various orders' corrections to the algorithm, that include information about the commutators of the system's Hamiltonian. Inclusion of such corrections results in faster optimal quantum control's search with high precision, i.e. allows saving of computational resources.
