Algorithm for solving unconstrained unitary quantum brachistochrone problems
Francesco Campaioli, William Sloan, Kavan Modi, Felix A. Pollock · Physical Review A · 2019
The quantum brachistochrone problem (QBP) aims to find the optimal map steering a quantum system from a given initial state to a given final state in the minimum time, related to the quantum speed limit. An iterative method is introduced to solve the unconstrained, unitary QBP for mixed states. It could be interesting for quantum control applications.
