Abstract

A network element in a quantum network receives a hybrid frame including a classical header and a quantum payload. The network element processes the classical header for a length of time and generates a new classical header. The network element drops a portion of the quantum payload based on the length of time spent processing the classical header and updates the hybrid frame to include the new classical header and the quantum payload without the dropped portion.
