Future research should focus on developing adaptive coding strategies with quantum channel codes to further optimise performance in various transmission scenarios. Investigating how adaptive coding can be further refined in conjunction with advanced quantum channel coding techniques could lead to significant improvements in error resilience and overall data integrity. Additionally, exploring the integration of these adaptive coding methods with emerging quantum communication protocols will be essential to move towards practical applications of quantum communication systems. Moreover, it is crucial to analyse the performance of these systems for video transmission, as this would provide valuable insights into their efficiency and robustness in handling high-bandwidth media, especially since a significant portion of media traffic transmitted over communication systems consists of videos.
Conclusion: This study highlights the superior performance of adaptive coding based quantum communication systems compared to equivalent classical communication systems, particularly under challenging low SNR conditions. The proposed quantum system demonstrates exceptional noise resistance, achieving PSNR improvements up to 65 dB and SSIM values up to 0.9999 for HEIF images, and PSNR values up to 58 dB with SSIM values up to 0.9994 for JPEG images, while outperforming the equivalent classical system, especially at low SNR levels. This shows that quantum communication not only retains image quality more effectively but also outperforms classical methods in maintaining signal integrity, even when transmission conditions are less than ideal. The efficient utilisation of bandwidth and the effective error correction mechanisms inherent in the quantum communication system further enhance its performance, making it particularly suitable for applications that require high signal integrity. Overall, this study highlights the significant potential of quantum communication techniques to improve image transmission quality in challenging environments, demonstrating their potential for real-world implementations where media transmission systems must operate in bandwidth-restricted environments.
