Entangled photons are distributed over vast distances using a satellite-to-ground link.
We perform decoy-state quantum key distribution between a low-Earth-orbit satellite and multiple ground stations located in Xinglong, Nanshan, Graz, which establish satellite-to-ground secure keys with ~kHz rate per passage of the Micius over station. The thus establishes itself and, say, another Graz. Then, upon request from command, acts as trusted relay. It performs bitwise exclusive OR operations two relays result to one stations. That way, secret is created China Europe at locations...
Quantum technology establishes a foundation for secure communication via quantum key distribution (QKD). In the last two decades, rapid development of QKD makes global network feasible. order to construct this network, it is economical consider small-sized and low-cost payloads, which can be assembled on satellites with different sizes, such as space stations. Here we report an experimental demonstration space-to-ground using payload, from Tiangong-2 lab Nanshan ground station. The 57.9-kg...
Free-space quantum key distribution (QKD) is important to realize a global-scale communication network. However, performing QKD in daylight against the strong background light noise major challenge. Here, we develop stochastic parallel gradient descent (SPGD) algorithm with deformable mirror improve signal-to-noise ratio (SNR). We then experimentally demonstrate free-space presence of urban daylight. The final secure rate 98∼419 bps throughout majority hours.
Significant progress has been made in satellite-based quantum key distribution (QKD), and urgent follow-up work is to explore the optimal solution for building practical constellations. Here, we demonstrate successful QKD based on compact terminal Tiangong-2 Space Lab construct a space–ground network among four ground stations. The medium-inclination orbit of can obtain multiple available passes same station one night, increasing generation amount directly. Further analysis results show that...
Multilabel learning involving hundreds of thousands or even millions labels is referred to as extreme multilabel (XML), in which the often follow a power-law distribution with majority occurring very few data points <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">tail labels</i> . Recent years have witnessed intensive use deep-learning methods for high-performance XML, but they are typically optimized head abundant training instances and less...
Abstract A model of simultaneous transport in hygroscopic porous materials was developed. Water fabrics is considered to be present three forms: liquid water the void space between fibers, bound and vapor. It assumed that heat mass mechanisms include movement due capillarity atmospheric pressure gradient, diffusion vapor within interfibers partial gradient total gas into fiber, evaporation, condensation water. The moisture process such as wool simulated. At normal pressure, results were...
Polarization maintenance is a key technology for free-space quantum communication. In this paper, we describe polarization design of transmitting antenna with an average extinction ratio 887 : 1 by local test. We implemented feasible polarization-compensation scheme satellite motions that has fidelity more than 0.995. Finally, distribute entanglement to from ground the first time violation Bell inequality 2.312+-0.096.
The influence of clothing material on thermal responses the human body are investigated by using an integrated model a clothed thermoregulatory body. A modified 25-nodes considering sweat accumulation skin surface is applied to simulate physiological regulatory responses. heat and moisture coupled transfer mechanisms, including water vapour diffusion, evaporation/condensation, sorbtion/desorption fibres, liquid under capillary pressure, latent absorption/release due phase change, considered...
Quantum key distribution (QKD) uses the fundamental principles of quantum mechanics to share unconditionally secure keys between distant users. Previous works based on science satellite "Micius" have initially demonstrated feasibility a global QKD network. However, practical applications space-based still face many technical problems, such as huge size and weight ground stations required receive signals. Here, we report space-to-ground demonstrations portable receiving stations. The station...
The scaled boundary finite element method (SBFEM) is used to solve the seepage problems with multi-material regions. Two models of dam base waterproof screen and body regions two materials are established. numerical solutions obtained then compared analytical results or in references. conclusion shows that SBFEM has more satisfactory accuracy less data preparation amount.
