    "abstract": "Precision control of a quantum system requires accurate determination of the\neffective system Hamiltonian. We develop a method for estimating the\nHamiltonian parameters for some unknown two-state system and providing\nuncertainty bounds on these parameters. This method requires only one\nmeasurement basis and the ability to initialise the system in some arbitrary\nstate which is not an eigenstate of the Hamiltonian in question. The scaling of\nthe uncertainty is studied for large numbers of measurements and found to be\nproportional to one on the square-root of the number of measurements.",
