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.

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 quantum orchestration platform (QOP) comprises a collection of processing units and analog components that produce synchronized analog pulses, readouts, and computations that may be used for operations with qubits. All processing units of the QOP are synchronized with minimal skew via time processing over one or more sync cables that interconnect the processing units.
