Systems and methods for scheduling usage time for programs that can be executed on a hybrid computing system including a quantum processing unit (QPU) and a central processing unit (CPU). Programs can comprise both QPU-executable tasks and CPU-executable tasks. Some programs can be considered high performance programs that are intolerant of interruptions to QPU-executable tasks and some programs can be considered low performance programs that are tolerant of interruptions to QPU-executable tasks. After a high performance program finishes executing QPU-executable tasks on a QPU, a low performance program may execute QPU-executable tasks on the QPU while the high performance program executes CPU-executable tasks on a CPU. Execution of QPU-executable tasks of a low performance program on a QPU can pause or stop if a high performance program is queued.
