Summary: We demonstrate photon-counting single-pixel imaging in the ultraviolet region using a 4H-SiC single-photon avalanche diode (SPAD) as a high-performance compact single-photon detector. By developing a tailored readout circuit with active hold-off time, we restrain detector noise and operate the SPAD in the free-running mode. With structured illumination, we reconstruct compressed images at a 4 fps frame rate, demonstrating the capability of ultraviolet imaging applications.

Summary: This paper proposes an approach to reduce the resource costs for quantum teleportation of subspaces in high-dimensional systems using quantum autoencoders and demonstrates it experimentally on an integrated photonic platform. By training the on-chip autoencoder with unsupervised machine learning, compression and teleportation of any state from a high-dimensional subspace are achieved.

Summary: Fourier single-pixel imaging (FSI) technique allows reconstruction of images by acquiring their Fourier spectrum using a single-pixel detector. A new sampling strategy is proposed to achieve clear and sharp image reconstruction with reduced measurements, enabling efficient spatial information acquisition. The method demonstrates the ability to reconstruct a sharp and clear 256 x 256 pixel image with a sampling ratio of 10%, providing a new approach for fast single-pixel imaging.

Summary: This study theoretically formalizes and experimentally demonstrates a notion of genuine high-dimensional quantum steering, showing that higher-dimensional quantum entanglement can lead to stronger steering. Simple two-setting steering inequalities are derived to certify the presence of genuine high-dimensional steering, based on the connection between steering and incompatibility of quantum measurements. The experimental violation of these inequalities using macropixel photon-pair entanglement certifies genuine high-dimensional steering, with a reported minimum Schmidt number of n = 15 for an entangled state in dimension d = 31.

Summary: In this paper, we propose a novel SAR imaging method that combines compressive sensing and autofocus technique to address the degradation in SAR image quality. By integrating the observation model and CS reconstruction problem, and considering phase errors and low-rate sampled dataset, an efficient iterative method is introduced to simultaneously perform SAR image formation and phase error correction.

Summary: In this study, a deep compressive sensing framework is proposed for image reconstruction in single-pixel imaging (SPI), addressing the challenges of spectrum truncation and discretization effects. A novel compression network is introduced to achieve collaborative sparsity in a discretized feature space and maintain coherence with the sensing basis. The method is trained in an unsupervised manner, mitigating the limitations of supervised training and showcasing promising results in validation experiments.

Summary: The single-pixel camera is developed to address the limitations faced by conventional cameras in invisible wavelengths and low light conditions, proposing a new method that utilizes compressive sensing technology and spatially variant resolution to optimize image reconstruction. Results show that SVR images can be reconstructed from fewer measurements and achieve better image quality compared to uniform resolution images.

Summary: A novel double color image encryption algorithm combining 2D compressive sensing with an embedding technique is proposed in this paper, achieving compression and encryption simultaneously and obtaining visually meaningful cipher images. Confusion of the compressed cipher images is done by index sequences generated from a 6D hyperchaotic system, while the relationship of the algorithm with plain images is enhanced by embedding feature parameters into the carrier image.

Summary: Compressive sensing aims to achieve high fidelity image recovery with a low number of measurements using an encoding scheme based on filtering the scene. The structured measurement matrix formed by the encoding patterns, which are linearly independent vectors, allows relatively well-conditioned dictionaries to be created using different sparsifying bases.
