Quantum payload service for facilitating communications between a quantum computing system and classical computing systems

A quantum computing system, comprising:

• one or more memories;
• and
• one or more processor devices coupled to the one or more memories to:
• receive, by a payload service, a message from a classical computing system that is destined for a first quantum service of a plurality of quantum services in the quantum computing system, the message including a header and a payload;
• determine, from the header, an originator address and a destination quantum service identifier that identifies the first quantum service;
• extract, from the message, the payload;
• send the payload, the originator address and the destination quantum service identifier to a quantum channel router of the quantum computing system for delivery of the payload to the first quantum service;
• generate, by the quantum channel router, a first quantum service message that comprises information that identifies the first quantum service, the originator address, and the payload;
• access, by the quantum channel router, a router table to identify, based on the destination quantum service identifier, a first quantum channel of a plurality of different quantum channels, wherein the quantum channel router is configured to communicate both classical and quantum information with the plurality of quantum services via the plurality of different quantum channels;
• determine, by the quantum channel router, that a current channel load of the first quantum channel is below a threshold channel load;
• and
• in response to determining that the current channel load of the first quantum channel is below the threshold channel load, send, by the quantum channel router, the first quantum service message on the first quantum channel.

A computer program product stored on a non-transitory computer-readable storage medium and including instructions configured to cause one or more processor devices to:

• receive, by a payload service in a quantum computing system, a message from a classical computing system that is destined for a first quantum service of a plurality of quantum services in the quantum computing system, the message including a header and a payload;
• determine, from the header, an originator address and a destination quantum service identifier that identifies the first quantum service;
• extract, from the message, the payload;
• send the payload, the originator address and the destination quantum service identifier to a quantum channel router of the quantum computing system for delivery of the payload to the first quantum service via a first quantum channel of a plurality of different quantum channels, wherein the quantum channel router is configured to communicate both classical and quantum information with the plurality of quantum services via the plurality of different quantum channels;
• receive a reply message from the first quantum service;
• determine that the reply message comprises a plurality of qubits;
• convert the plurality of qubits in the reply message into a plurality of classical bits, each of which has a value of one or zero, to generate a classical bit reply message;
• generate a Hypertext Transfer Protocol (HTTP) header that includes a destination address, the destination address comprising the originator address;
• generate a new message that includes the HTTP header and the classical bit reply message;
• and
• send the new message to the classical computing system via the destination address.
