With the advancements in satellite communication, there arises a demand for the secure transmission of satellite and remote sensing images to the ground monitoring stations which has significant challenges due to the increased threat of cyber-attacks and the sensitive nature of those images. Existing classical cryptography methods fail to meet the advanced security demands. Thus, there arises a need for advanced cryptography techniques which ensure secure transmission of data in satellite communication. Recent advancements in quantum computing and research have shown that leveraging quantum mechanics and principles enhances security. We propose a novel quantum-based image encryption technique for securing satellite and remote sensing images during transmission named QCrypt. QCrypt utilizes the power of quantum chaotic maps, classic chaotic maps, and DNA encoding techniques to ensure the security of the images. QCrypt has been tested using a remote sensing image dataset and achieved increased performance in terms of resistance to histogram analysis, differential attacks, and chosen- plaintext attacks compared to traditional encryption methods. Our approach addresses the critical need for secure satellite data transmission and the use of quantum-based encryption to meet security demands.

We compare the performance of quantum imaging schemes based on spatially correlated photon pairs by formulating them as quantum multiparameter estimation problems, in which the object is characterized by transmission coefficients associated with different spatial modes. Our work focuses on standard quantum imaging techniques such as ghost imaging, two-photon imaging, and imaging with undetected photons. Specifically, we compute the quantum Fisher information matrices and show that they are saturated by Fisher information matrices corresponding to measurements in the object-mode basis, which generalize the common detection schemes employed in each imaging configuration. We find that ghost imaging and two-photon imaging generally provide higher precision for transmission estimation than imaging with undetected photons, but the latter is the only one that naturally does not couple transmission estimation across different spatial modes. These results identify which imaging protocols are best suited for specific tasks and provide practical guidelines for the design and optimization of quantum sensing technologies based on spatial correlations.

Modeling of image transmission with a classic quantum computer interpreter is suggested.The transmission algorithm from the paper (Lemos G.B., et.al.Quantum Imaging with Undetected Photons, Nature, 2014, 512, P. 409-412) is modified to reduce the complexity of the quantum circuit.Simplification was done by replacing the non-linear optical elements with a conventional quantum entanglement operator.The obtained results show expected efficiency of data transmission with Gaussian beam by hypothesis test and calculation error function.This error function is used for quality measurement.The interpreter is written in Kotlin language.
