In one example, a processor device of a staging computing device (i.e., a classical non-quantum computing device) receives an operating parameter from a quantum computing device, wherein the operating parameter represents an operating condition of the quantum computing device. The processor device also receives a quantum service definition that defines a quantum service. A quantum simulator of the processor device accesses the quantum service definition, simulates the operating condition of the quantum computing device based on the operating parameter, and then executes the quantum service under the simulated operating condition based on the quantum service definition. ## Claims ### Claim 1 A method, comprising: receiving, by a staging computing device, an operating parameter from a particular quantum computing device, wherein the operating parameter represents an actual operating condition of the particular quantum computing device;
