Quantum-optical communication systems offer a high data rate with unmatched security aspects. This paper presents a novel approach to implement the superdense coding technique using Chua’s oscillator in a quantum-optical channel environment. To enhance the encoding process, the chaotic behaviour of Chua’s oscillator is utilized. The high data transmission rate is maintained while the resistance against the eavesdropping attempts has been increased due to the principle of quantum mechanics. In comparison to the classical channel, the double speed data rate in the quantum-optical channel will be achieved due to the quantum entanglement-enabled model. In this, two informative classical bits are sent with a single photon. The realization of the proposed model is performed on Qiskit simulator. The noise analysis of the proposed quantum circuit is discussed in detail, along with fidelity and decoherence measures. The security aspect and computational & hardware complexity are also analyzed. This work contributes to the advancement of secure quantum communications to help in the design of next-generation cryptographic systems.
