Quantum Controller With Modular And Dynamic Pulse Generation And Routing
A quantum controller comprises raw pulse generation circuitry, pulse modification circuitry, and output management circuitry. The raw pulse generation circuitry is operable to generate a raw output pulse. The output management circuitry is operable to route one or more output pulses onto a selected one or more signal paths based on to which one or more of a plurality of elements of a quantum processor the one or more output pulses are to be sent. 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.
