Abstract
  • The rapid growth of image and video applications has exposed fundamental limitations in existing communication systems. Unlike conventional data, multimedia content consists of large data volumes and requires the reliable preservation of perceptual quality under stringent bandwidth constraints and in the presence of channel noise. Existing communication systems rely on binary representations that are highly susceptible to channel impairments, where even minor transmission errors can significantly degrade reconstructed quality. Although quantum communication has the potential to overcome these limitations by exploiting the principles of quantum mechanics, existing research has primarily focused on secure information exchange, while its application to end-to-end high-fidelity communication remains unexplored. Motivated by these gaps, this thesis proposes a new multimedia-oriented quantum communication paradigm for image and video transmission that rethinks how multimedia information is represented, protected, compressed, transmitted, and reconstructed over noisy communication channels. The proposed paradigm is progressively developed through a series of interconnected contributions. First, an end to-end quantum communication framework based on Hadamard superposition encoding is established with and without quantum error correction. Second, multi-qubit encoding strategies map multimedia data into higher-dimensional Hilbert spaces to improve transmission robustness and bandwidth efficiency. Third, the framework is extended through quantum frequency-domain transformations, enabling frequency domain multimedia transmission and high-ratio compression. Fourth, a novel complex valued orthogonal unitary superposition (COUS) encoding framework jointly exploits amplitude and phase diversity to enhance robustness while maintaining linear gate complexity. Finally, the proposed paradigm is integrated with multiple input multiple-output (MIMO), orthogonal frequency-division multiplexing (OFDM), hybrid MIMO-OFDM, multiple description coding (MDC), and semantic communication systems, demonstrating its applicability to practical multimedia communication systems. Extensive simulation results demonstrate that the proposed paradigm consistently outperforms conventional communication systems by improving transmission robustness, reconstruction quality, compression efficiency, and semantic reliability under noisy channel conditions. Collectively, these findings establish a scalable foundation for next-generation multimedia communication systems.
