The pulse modification circuitry is operable to select pulse modification settings to use for processing of the raw output pulse, wherein the selection is based on which of the signal paths are selected and/or to which elements of a quantum processor the pulses are to be sent. The pulse modification circuitry is operable to process the raw pulse using the selected pulse modification settings to generate the output pulses.

Abstract: A pulse generation circuit in a quantum controller operates synchronously with a pulse computation circuit. The pulse generation circuit generates a pulse associated with a quantum element operation. The pulse computation circuit is able to determine characteristics of a signal that is based on the pulse. These characteristics are used by the pulse generation circuit to modify the pulse.

Abstract: In a quantum computer, quantum algorithms are performed by exciting a qubit with a quantum control pulse. This quantum control pulse is an electromagnetic RF signal that is generated at baseband according to an analog waveform. An application digitally generates samples of this analog waveform using multiple classical processors that control multiple physical channels in parallel.

Abstract: This disclosure describes an auto-calibration of mixers in a quantum orchestration platform. Predistortion is computed according to an RF signal that is downconverted with a local oscillator tone that is offset from an upconverter tone. Three tones present in the original RF signal are distinguished and used to construct a cost function. The minimization of the cost function is used to cancel an unwanted LO leakage and an image tone. Because the quantum orchestration platform generates both the unconverted IQ signals and the cost function for their optimization, the optimization can be performed in real time inside a single device without the need to communicate with external devices. This allows for the optimization of single sideband upconverted signals in a fraction of the time it typically takes using distributed systems employing separate waveform generators and spectrum analyzers.

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.
