Claim 12:
13. A system for controlling a spin system in an external magnetic field, comprising:
a resonator configured to generate a magnetic field in response to receiving pulses from a control system, the magnetic field applied to the spin system; and
the control system, coupled to the resonator and configured to perform operations comprising:
defining a target operation to be performed on the spin system,
generating a sequence of parameters that represent the target operation and establish a control sequence for the resonator,
converting the control sequence into successive pairs of first and second pulses,
sending the successive pairs of first and second pulses to the resonator by alternately,
sending a first pulse to the resonator over a first period,
sending a second pulse to the resonator over a second period immediately following the first period,
wherein each first pulse maintains the magnetic field generated by the resonator in a transient state during the first period,
wherein the resonator alters a magnitude of the generated magnetic field to zero in response to each received second pulse, and
wherein the control sequence corresponds to a shaped pulse that:
suppresses hysteretic effects of the resonator by driving a magnetic field produced by the resonator to zero at the beginning and end of each successive pair of first and second pulses, and
provides control that is insensitive to variations in parameters of the resonator by maintaining the magnetic field in a transient state.
