    Abstract: A system comprises time-tracking circuitry and phase parameter generation circuitry. The time-tracking circuitry is operable to generate a time-tracking value corresponding to time elapsed since a reference time. The phase parameter generation circuitry operable to: receive the time-tracking value; receive a control signal that conveys a frequency parameter corresponding to a desired frequency of an oscillating signal; and generate a plurality of phase parameters used for generation of an oscillating signal, wherein the generation of the plurality of phase parameters is based on the time-tracking value and the frequency parameter such that the oscillating signal maintains phase continuity across changes in the frequency parameter.

    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.

    Abstract: A system comprises quantum control interconnect circuitry configured to receive a plurality of fixed-frequency signals, a variable-frequency signal, a quantum control pulse, a quantum element readout pulse, and a quantum element return pulse. The circuitry is operable to upconvert the quantum control pulse using the fixed-frequency signals. The circuitry is operable to upconvert the readout pulse using the variable-frequency signal. The circuitry is operable to downconvert the return pulse using the variable-frequency signal.
