1. A method comprising:
receiving a hybrid frame at a router in a quantum network, the hybrid frame including a classical header and a quantum payload;
processing the classical header for a length of time;
generating a new classical header;
dropping a portion of the quantum payload based on the length of time spent processing the classical header; and
updating the hybrid frame to include the new classical header and the quantum payload without the dropped portion.
