Quantum communications for image transmission over error‐prone channels

Udara Jayasinghe, Prabhath Samarathunga, Yasith Ganearachchi +2 more

Abstract The introduction of quantum communications, enabled by advancements in quantum computing, is expected to play a significant role in the field of communications. Inherent properties of quantum objects, such as superposition and entanglement, have the potential to provide novel solutions to overcome the challenges encountered by classical communication systems in bandwidth‐intensive applications such as media transmission. This research explores the performance of a quantum communication system in image transmission using quantum superposition and investigates its performance using a simple quantum channel model. With an increase in channel noise, there are significant gains in the rate distortion performance of images transmitted over the quantum channel compared to an ideal classical channel. This novel attempt at constructing a quantum communication‐based image transmission system indicates the potential of the approach to be applied to satisfy the ever‐increasing demands of high‐quality media transmission applications.

Nonlocal wavefront shaping through complex media

Yanis Trouyet, Neelan Gounden, Pedro Ornelas +3 more

Wavefront shaping is a key technique for mitigating scattering in complex media, enabling advanced imaging and optical communication. Yet existing approaches are inherently local, requiring active correction elements - such as spatial light modulators or deformable mirrors - to lie directly in the optical path of the scattered light, which limits their integration into compact imaging systems. Here, we experimentally demonstrate nonlocal wavefront shaping using spatially entangled photon pairs. By applying a phase correction to a photon that never interacts with the scattering medium, we compensate for the distortions experienced by its entangled partner and restore their initial spatial correlations. Our approach physically decouples the wavefront correction from the scattering medium, paving the way for imaging through complex media in compact and otherwise inaccessible systems.

Image Transmission Over Quantum Communication Systems With Three‐Qubit Error Correction

Udara Jayasinghe, Prabhath Samarathunga, Thanuj Fernando +2 more

ABSTRACT Quantum communication offers unparalleled reliability and efficiency, making it a promising solution for high‐quality media transmission. To explore this potential, we propose a quantum communication system for image transmission, addressing the challenges of transmitting high‐quality image data over error‐prone channels. A crucial aspect of advancing this field is quantum channel coding, specific to quantum systems. Therefore, this research evaluates the performance of low‐complex three‐qubit quantum error correction code for image transmission over noisy channels. JPEG and HEIF images are encoded using three‐qubit error correction method and compared to 1/3 rate polar codes with equivalent bandwidth. Results show that the three‐qubit error correction code significantly outperforms advanced classical polar codes in both classical and quantum domains, achieving a maximum PSNR of 64.5 dB (SSIM = 0.9997) in HEIF and 58.3 dB (SSIM = 0.9994) in JPEG. These findings underscore its potential as a robust solution for quantum communication in media transmission.
