A method and quantum computing device for preempting a quantum program. A first quantum circuit is executed by a quantum processor to process a first job of the quantum program for a number of shots, where the number of shots defines how many times a quantum circuit is to be repeatedly executed. The execution of the first quantum circuit to process the first job is then preempted, such as to allow a higher priority and/or shorter-running job to be processed. Upon preempting the execution of the first quantum circuit, the quantum processor executes a second quantum circuit to process a second job (e.g., higher priority and/or shorter-running job to be processed). Upon completion or preemption of the execution of the second quantum circuit to process the second job, the quantum processor completes the execution of the first quantum circuit to process the first job.

Preempting a quantum program in a quantum computing device

One or more systems, devices, computer program products and/or computer-implemented methods of use provided herein relate to usage maximization of a physical qubit layout of a quantum computer. A system can comprise a memory that stores computer executable components, and a processor that executes the computer executable components stored in the memory, wherein the computer executable components can comprise an identification component that identifies a quantum circuit, and a scheduler component that maps the quantum circuit to a physical qubit layout. In an embodiment, the scheduler component can combine plural quantum circuits, including the quantum circuit into a composite circuit, and map the composite circuit to the physical qubit layout. In an embodiment, an obtaining component can assign the quantum circuit to a temporary storage bucket and can identify whether the temporary storage bucket meets a threshold where the scheduler component can proceed to analyze the quantum circuit.

Quantum circuit buffering

Techniques facilitating quick waveform revisions following quantum system calibrations. In one example, a system can comprise a processor that executes computer executable components stored in memory. The computer executable components comprise: a calibration component; and a regeneration component. The calibration component can identify a parameter of a directed graph changed by a calibration of a quantum system that occurs after generation of the directed graph. The regeneration component can revise the directed graph based on the identified parameter to generate an updated directed graph.
