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.

Pulse generation in a quantum device operator

In a quantum computer, quantum algorithms are performed by a qubit interacting 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 circuit digitally generates samples of this analog waveform. These waveform samples are further modified according to post-processing instructions. To avoid processing gaps, the waveform samples and the modification instructions are maintained in buffers that are accessed independently. To maintain coherency, the waveform samples and the modification instructions are read simultaneously by an execution controller.

Classical processor for quantum control

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.
