In the context of integrating quantum principles into the Internet of Things (IoT) network to enhance capacity, security, and resilience, we present a classical-quantum (CQ) protocol stack that can be systematically integrated into a classical network. The CQ architecture explicitly defines the physical and link layer behavior to accommodate quantum functionalities. We demonstrate how the use of classical error correction codes (ECC) is practical within a quantum communication protocol integrated into a classical network setup. Furthermore, we have modeled a method to calculate the classical capacity of quantum-assisted transmission over a noisy quantum channel that employs classical ECC. As a proof of concept, we have emulated classical packet transmission through various layers of the proposed protocol stack, and the behavior has been analyzed.
