Microwave-based satellite–ground links are used to transfer time and frequency in various applications such as metrology, navigation, positioning, very long baseline interferometers. The existing approaches, however, cannot fully satisfy the requirements of these applications. In this study, we investigated possibility an optical-based link, where transferred carriers pulsed lasers, resulting a link with high resolution large ambiguous range. First, analyzed parameters satellites different...
Remote sensing can efficiently acquire information and is widely used in many areas. Object detection a key component most applications. But complex backgrounds remote images severely degrade performance. Current methods fail to effectively suppress background interference while maintaining fast speeds. This paper proposes Attention-Guided Yolo (AG-Yolo), an efficient oriented object (OOD) method tailored for sensing. AG-Yolo incorporates additional rotation parameter into the head of...
Quantum mechanics is commonly formulated in a complex, rather than real, Hilbert space. However, whether quantum theory really needs the participation of complex numbers has been debated ever since its birth. Recently, Bell-like test an entanglement-swapping scenario proposed to distinguish standard from real-valued analog. Previous experiments have conceptually demonstrated, yet not satisfied, central requirement independent state preparation and measurements leave several loopholes. Here,...

Numerous demonstrations have been reported self-test various types entangled states. However, all multiparticle so far suffer from both detection locality loopholes. Here, we report first experimental realization entanglement closing loophole photonic system, superconducting respectively. We certify three-party four-party GHZ states with...
Nonlocality captures one of the counterintuitive features nature that defies classical intuition. Recent investigations reveal our physical world's nonlocality is at least tripartite; i.e., genuinely tripartite nonlocal correlations in cannot be reproduced by any causal theory involving bipartite nonclassical resources and unlimited shared randomness. Here, allowing fair sampling assumption postselection, we experimentally demonstrate such genuine a network under strict locality constraints...
