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.
