Some em- bodiments of the waveform processor may be used to control quantum systems used in quantum computation, such as qubits. Ac- cording to some embodiments, a waveform processor may include a first sequencer configured to sequentially execute master in- structions according to a defined order and output digital values in response to the executed master instructions, and a second se- quencer coupled to the first sequencer and configured to generate analog waveforms at least in part by transforming digital wave- forms according to digital values received from the first sequencer. The analog waveforms may be applied to a quantum system. In some embodiments, the waveform processor may further include a waveform analyzer configured to integrate analog waveforms re- ceived from a quantum system and output results of said integration to the first sequencer.
