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: 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 set of quantum controllers are operable to transmit quantum state data to a quantum control switch. The quantum control switch comprises vector processors that operate on the quantum state data from the set of quantum controllers. Each vector processor transmits a result of the operation to a corresponding quantum controller in the set of quantum controllers.

Abstract: Methods and systems for classical processing in a quantum controller are operable to receive data from a quantum processor and demodulate a feedback pulse according to a command, a vector of digital samples and a vector of quadrature reference inputs. The vector of digital samples correspond to a feedback pulse from the quantum processor at a first time, and the vector of quadrature reference inputs correspond to a phase and a frequency at a second time. Exemplary embodiments of the methods and systems for classical processing in the quantum controller are also operable to perform one or more ALU, CLU, Boolean and multiplication operations in parallel with demodulation.

Abstract: Quantum algorithms are performed via a quantum computer, by generating a quantum control pulse in a quantum controller and transmitting the quantum control pulse to a quantum processor. The quantum control pulse interacts with a qubit in the quantum processor. Within the quantum controller, a pulse processor generates a plurality of raw pulses that are modified by a front end hardware module. During the normal operation of the quantum controller, samples of the raw and/or modified pulses may be selected and saved to memory. During a design for validation (DFV) mode, the proper operation of the quantum controller is determined according to a simulation of the quantum controller and the saved samples. The DFV mode may be performed in parallel with normal operation without affecting the resources of the quantum controller.

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.
