Frequency management for quantum control

A system comprising:

• a quantum control pulse generation circuit operable to generate a quantum control pulse;
• and
• a multi-tone generation circuit operably coupled to the quantum control pulse generation circuit, wherein:
• the multi-tone generation is operable to generate a plurality of fixed-frequency signals,
• each of the plurality of fixed-frequency signals is at a different one of a plurality of frequencies from a first frequency to a second frequency,
• any frequency, from the first frequency to the second frequency, can be achieved by tuning the quantum control pulse, and
• frequency spacing between frequency-adjacent signals of the plurality of fixed-frequency signals is less than or equal to the range of frequencies over which the quantum control pulse generation circuit is operable to generate the quantum control pulse.
