Summary:
- Investigates the effectiveness of forward error correction (FEC) in Quantum Secure Direct Communication (QSDC) systems employing a QPSK-like protocol.
- Using platforms like IBMQ and NetSquid, the analysis reveals that FEC alone cannot guarantee error-free transmission with current qubit fidelities.
- Reliable, error-free operation requires qubit fidelity above ~0.981, highlighting current hardware limitations and guiding future system development.
This work underscores the importance of pursuing both advanced QSDC protocols and hardware improvements for secure quantum communication.
