Abstract: In a quantum computer, quantum algorithms are performed by a qubit interacting with multiple quantum control pulses. The quantum control pulses are electromagnetic RF signals that are generated digitally at baseband and sent, via asynchronous ports, to DACs that feed an RF upconversion circuit. For synchronization, each asynchronous port is coupled to a multi-tap delay line. The setting of the multi-tap delay line is determined by a function of the port's setup-and-hold time. This function is trained, via machine learning, to be applicable across a variety of ports.

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: A channel between quantum controller modules (e.g., pulse processors) is operable to communicate high speed data required for processing qubit states that may be distributed across a quantum computer. The latency of the communication channel is deterministic and controllable according to a system clock domain.

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.
