Quantum channel routing utilizing a quantum channel measurement service

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 quantum channel router communicatively coupled to a plurality of quantum channels, a first message from a first sender of a plurality of senders, the first message directed to a first receiver of a plurality of receivers, wherein each quantum channel is configured to convey a quantum message from a sender to a receiver;
• identify, by the quantum channel router, a first quantum channel to which the first receiver listens;
• determine, by the quantum channel router, a first message size of the first message;
• determine that transmission of the first message would exceed a maximum channel capacity of the first quantum channel at a current point in time;
• and
• in response to determining that transmission of the first message would exceed the maximum channel capacity of the first quantum channel, not transmit the first message onto the first quantum channel at the current point in time.

A non-transitory computer-readable storage medium that includes executable instructions configured to cause one or more processor devices to:

• receive, by a quantum channel router communicatively coupled to a plurality of quantum channels, a first message from a first sender of a plurality of senders, the first message directed to a first receiver of a plurality of receivers, wherein each quantum channel is configured to convey a quantum message from a sender to a receiver;
• identify, by the quantum channel router, a first quantum channel to which the first receiver listens;
• determine, by the quantum channel router, a first message size of the first message;
• determine that transmission of the first message would exceed a maximum channel capacity of the first quantum channel at a current point in time;
• and
• in response to determining that transmission of the first message would exceed the maximum channel capacity of the first quantum channel, not transmit the first message onto the first quantum channel at the current point in time.
