The teams from Peking University and Zhejiang University have successfully developed the world's first quantum entangled vortex light emitting chip through cooperation. With a size of only 5?0 millimeters, it can Programmable control and microsecond level manipulation. It’s OAM light field can support infinite-dimensional information encoding, which increases the capacity of quantum communication several times. Moreover, it can be stably transmitted in optical fibers, opening up new application avenues for fields such as high-dimensional quantum communication, quantum precision measurement, and on-chip ion and atom manipulation.
The reviewers of journal Nature commented: ‘This work has achieved multi-bit continuous variable quantum entanglement on an optical quantum chip for the first time, marking an important milestone in scalable optical quantum information processing.’
Ubtech Robotics carried out the world's first collaborative training of humanoid robots with multiple units, in multiple scenarios and for multiple tasks, at Geely's ZEEKR 5G smart factory. Dozens of Walker S1 robots were deployed in scenarios such as final assembly and quality inspection, performing tasks including sorting, handling and precision assembly. This initiative aims to explore and establish a general solution for group operations of humanoid robots in multi - task industrial scenarios, and promote the evolution of humanoid robots from single - unit autonomy to group intelligence.
China's largest photovoltaic project in a coal mining subsidence area has been put into operation in Ordos, Inner Mongolia. With an installed capacity of 3,000 megawatts and covering an area of 105,000 mu, a total of 5.9 million photovoltaic panels have been laid. It can generate up to 5.7 billion kilowatt-hours of electricity annually, which is sufficient to power 2 million households. Additionally, it can reduce carbon dioxide emissions by 4.7 million tons each year.
The project directly transmits green electricity to Shandong through ultra-high voltage direct current transmission, achieving the remarkable feat of "transmitting electricity from the west to the east." It also contributes to the management of sandy and desertified areas and the transformation of the energy sector.
The fifth model in the Huawei Mate 70 series, the Exclusive Edition of Huawei Mate 70 Pro, has officially gone on sale. It is available in three versions: 12GB + 256GB, 12GB + 512GB, and 12GB + 1TB. The overall performance of the Exclusive Edition of Huawei Mate 70 Pro is 35% higher than that of the Huawei Mate 60 Pro.
The world's first half - marathon for humanoid robots will be held during the Beijing Yizhuang Half - Marathon on April 13th. At that time, humanoid robots will start running at the same time as the athletes at the starting point, sharing the same route.
