In a general aspect, a computer system includes a low-latency communication link between a classical computer and a quantum computing resource. In some cases, a quantum machine image operates on a classical computer system. The quantum machine image includes a virtualized execution environment for quantum programs. The quantum machine image is engaged with a quantum processing unit of a quantum computing system. A quantum program is communicated over a low-latency communication pathway from the classical computer system to the quantum computer system. The quantum program is executed at the quantum computer system.

Low-latency, high-performance hybrid computing

In a general aspect, a quantum computing method is described. In some aspects, a control system in a quantum computing system assigns subsets of qubit devices in a quantum processor to respective cores. The control system identifies boundary qubit devices residing between the cores in the quantum processor and generates control sequences for each respective core. A signal delivery system in communication with the control system and the quantum processor receives control signals to execute the control sequences, and the control signals are applied to the respective cores in the quantum processor.

Modular control in a quantum computing system

In a general aspect, a method executed in a quantum computing system includes performing a calibration process in the quantum computing system to identify a value of a parameter of the quantum computing system. The method also includes analyzing a variation of the value in response to a change in a condition of the quantum computing system, thereby determining a stability of the parameter. The method additionally includes scheduling a recalibration of the parameter based on the stability of the parameter and executing a quantum algorithm in the quantum computing system based on the value of the parameter identified by the calibration process.

Maintaining calibration in a quantum computing system

In a general aspect, quantum computing system performance is tested. Systems and methods for testing hardware in a quantum computing system are described. The methods may include certification/decertification of data produced by the quantum computing system, detection of faults, correction of errors and/or recalibration/replacement of the quantum computing system or a quantum computing subsystem.
