A groundbreaking integrated encryption and communication (IEAC) framework, enabled by end-to-end deep learning, has achieved a record-breaking single-channel secure transmission rate of 1 Terabit per second (Tb/s) over a 1,200-km optical fibre link. Published in National Science Review, this innovation optimizes mutual information for legal users while minimizing leakage to eavesdroppers, offering a scalable solution for high-speed, secure data transmission in the era of big data and AI.

In a paper published in SCIENCE CHINA Earth Sciences, a team of researchers employed systematic archaeobotanical flotation and AMS radiocarbon dating at two sites in Romania: Baia-În Muchie and Dobrovăț. It provides valuable data on the chronology of millet cultivation in the SW Eastern European Plain and enhances our understanding of early East-West exchanges and their impact on human-environment interactions in critical regions.

Recently, Professor Peng Xue's team from the Beijing Computational Science Research Center published an article titled "Quantum cooling engine fueled by quantum measurements" in Science Bulletin. The research team employed a linear optical platform to simulate a two-stroke, two-qubit engine. In the experiment, they demonstrated various quantum thermodynamic processes by tuning the energy level spacing of the working substance and adjusting the temperature parameters of the bath. They successfully realized a quantum cooling engine driven by quantum measurements and discovered the influence of entanglement on the energy exchange between the working substance and the measurement apparatus.

A research team has developed an organic radical-activable charge-transfer (CT) cocrystal with a remarkable photothermal conversion efficiency of 67.2% for solar thermoelectric generators (STEGs). This innovation enables STEGs to generate 143 mV under 1 sun irradiation, offering a promising solution for self-powered wearable electronics and Internet of Things. The cocrystal's strong near-infrared absorption and nonradiative recombination properties pave the way for applications in non-contact information conversion and real-time photodetection.
