Classical management of qubit requests is provided. In particular, a classical computing device receives a payload from another classical computing device via a classical computing connection, such as a Hypertext Transfer Protocol (HTTP) connection. The classical computing device queries a quantum computing device regarding availability of a qubit, whether targeted or agnostic, according to instructions provided in the payload. Such instructions may include inserting data into a qubit, manipulating a qubit, and/or reserving a qubit. If the qubit is available, the classical computing device sends the payload to the quantum computing device. If the qubit is unavailable, the classical computing device continues to query the quantum computing device until the qubit is available. Such a configuration provides granular control of qubits by a classical computing device and/or shifts management loads from the quantum computing device to the classical computing device.
