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: A system comprises an electromagnetic pulse generation system that comprises a first pulse generation circuit, a second pulse generation circuit, and a mixing circuit. The electromagnetic pulse generation system is operable to output a first pulse generated by the first pulse generation circuit onto a first signal path, output a second pulse generated by the second pulse generation circuit onto the first signal path, generate a third pulse by mixing, via the mixing circuit, a fourth pulse generated by the first pulse generation circuit and a fifth pulse generated by the second pulse generation circuit, and output the third pulse on the first signal path.

Abstract: A controller comprises a pulse generation circuit, output management circuitry, and a plurality of outputs configured to connect the controller to a plurality of controlled elements. The pulse generation circuit is configured to generate quantum control pulses. For each control pulse of a plurality of control pulses generated by the pulse generation circuit, the output management circuitry is configured to determine to which of the plurality of outputs to route the control pulse such that a first of the plurality of control pulses is routed to a first of the plurality of controlled elements and a second of the plurality of control pulses is routed to a second of the plurality of control elements.

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.

Abstract: A system comprises pulse generation and measurement circuitry comprising a plurality of pulse generator circuits and a plurality of ports, and management circuitry. The management circuitry is operable to analyze a specification of a controlled system and controlled elements that comprises a definition of a controlled element of the control system, and a definition of one or more pulses available for transmission by the control system. The management circuitry is operable to configure, based on the specification, the pulse generation and measurement circuitry to: generate the one or more pulses via one or more of the plurality of pulse generator circuits; and output the one or more pulses to the controlled element via one or more of the plurality of ports.

Abstract: A quantum controller comprises a first outbound quantum control pulse generation circuit, a second outbound quantum control pulse generation circuit, and an outbound quantum control pulse modification circuit. The first outbound quantum control pulse generation circuit is operable to generate a first raw outbound quantum control pulse. The second outbound quantum control pulse generation circuit operable to generate a second raw outbound quantum control pulse. The outbound quantum control pulse modification circuit is operable to dynamically determine whether to process the first raw outbound quantum control pulse and the second outbound quantum control pulse as a multi-pulse pair or as two independent pulses. The determination of may be based on to which one or more quantum elements and/or signal paths the first raw outbound quantum control pulse and the second raw outbound quantum control pulse are to be routed.
