    Abstract: A quantum controller comprises quantum control pulse generation circuitry, signal generation circuitry, and phase parameter generation circuitry. The phase parameter generation circuitry is operable to determine, based on an output of the time-tracking circuitry, a first value of a phase parameter to be used for generation of an oscillating signal. The signal generation circuitry is operable to, at a first time instant, begin generation of the oscillating signal at a first frequency for modulation of a first of the two quantum control pulses, and, at a second time instant, generate the oscillating signal at a second frequency, wherein the phase of the oscillating signal at the second time instant is determined by the value of the phase parameter such that the phase of the oscillating signal is as it would have been if the oscillating signal had been oscillating at the second frequency continuously since a reference time.

    Abstract: A system comprises pulse program compiler circuitry operable to analyze a pulse program that includes a pulse operation statement, and to generate, based on the pulse program, machine code that, if loaded into a pulse generation and measurement circuit, configures the pulse generation and measurement circuit to generate one or more pulses and/or process one or more received pulses. The pulse operation statement may specify a first pulse to be generated, and a target of the first pulse. The pulse operation statement may specify parameters to be used for processing of a return signal resulting from transmission of the first pulse. The pulse operation statement may specify an expression to be used for processing of the first pulse by the pulse generation and measurement circuit before the pulse generation and measurement circuit sends the first pulse to the target.
