A Chinese research team has implemented the world’s first quantum secure direct communication (QSDC) system. The breakthrough provides a promising solution to counter threats in the area of communication security.
Beijing Academy of Quantum Information Sciences revealed at the 2020 ZGC Forum on Saturday that they have implemented the world’s first QSDC system.
The present system can operate with a communication rate of 4kb/s at a distance of 10 kilometers, bringing QSDC further toward practical applications.
Alibaba launched a cloud computer named “Wuying 无影” at its 2020 Computing Conference. The computer has no localhost or CPU, and all of its hardware is stored at the cloud end’s data center, reducing computing power by more than 50% if the cloud computer is widely used.
China successfully conducted its second sea launch mission with Long March-11 from waters in the Yellow Sea off the coast of East China’s Shandong Province on Tuesday, sending 9 satellites into orbit at the same time.
Compared to the first launch, developers have further optimized and streamlined its sea launch capabilities by deploying a new launch vessel and putting a new coastal spaceport into operation, laying a solid foundation for more frequent and regular sea missions in the future.
The launch mission from sea successfully sent a group of nine commercial remote sensing satellites, all belonging to the Jilin-1 03 family, into the 535-kilometer Sun-synchronous orbit (SSO).
Oracle has reportedly won a deal to manage TikTok’s US cloud operations. Oracle had been rumored to be part of the bidding process to acquire TikTok, but The Wall Street Journal reports that the company has been selected as a “trusted tech partner” instead. This is different from an outright sale, and appears to suggest Oracle will be helping run TikTok’s US operations with its own cloud technologies.
If Trump agrees to this, Tik Tok is poised to explode much bigger and it will open the door to more Chinese companies operating in the West. My guess is “not likely”.
Hawley calls for US to reject Oracle’s TikTok deal. The deal is currently awaiting a recommendation from the Committee on Foreign Investment in the United States (CFIUS), but it has received praise from Treasury Secretary Steve Mnuchin, who chairs the committee. In an open letter to Mnuchin, Hawley calls on the secretary to take a more skeptical look at the proposal.
Rubio has sent a letter to the Trump Administration urging it to reject the proposed Oracle-TikTok deal, which would leave TikTok as an independent, US-based company, because ByteDance, TikTok’s parent, will retain a majority stake.
Ted Cruz has joined Marco Rubio, Josh Hawley and others in opposing the deal, penning his own letter claiming that any deal that doesn’t 100% address national security concerns should be rejected.
09-02-20 Toronto-based Xanadu announced the release of the world’s first publicly available photonic quantum computing platform. Applicants can access 8, 12, and soon 24 qubit machines over the cloud.
The launch of the “Jilin-1 吉林一号 ” high-division 02C satellite by a Qizhou-1A carrier rocket from the Jiuquan Satellite Launch Centre was abnormal and the mission was lost. The specific causes are being further investigated and analysed.
Huawei unveils updated Harmony OS on Thursday – a self-developed operating system widely seen as alternative to Google Android – and gave its direct response to US escalated crackdown on its technology & supply chain. All Huawei Smartphones Will Support Harmony OS in 2021 Amid Android Ban.
Huawei released testing version of its updated self-developed operating system HarmonyOS 2.0 to developers, and it is scheduled to release a version for mobile phone in December, Yu noted. “HarmonyOS will be used in smartphones in next year,” he said.
The development is considered the Chinese tech giant’s direct response to the expanded ban from the Trump administration as the tech cold war between the US and China heats up and poses a severe threat to the global supply chain, particularly as September 15, the deadline for cutting off the supply of chipsets to Huawei looms.
Foreign Minister Wang Yi announced in Beijing a global data security initiative《全球数据安全倡议》 on Tuesday outlining principles that should be followed in areas from personal information to espionage.
China’s initiative has eight key points including not using technology to impair other countries’ critical infrastructure or steal data, and making sure service providers don’t install backdoors in their products and illegally obtain user data.
Wang also said the initiative looks to put an end to activities that “infringe upon personal information” and oppose using technology to conduct mass surveillance against other states.
Companies should also respect the laws of host countries and stop coercing domestic firms to store data generated overseas in their own territory, the initiative added.
Anyone signing up to the pledge should also respect the sovereignty, jurisdiction and governance of data of other states and avoid asking companies or individuals located in other countries to provide data without permission.
At the Taiyuan Satellite Launch Centre 太原卫星发射中心 , China successfully launched the Gaofen 11-02 高分十一号02星 into a predetermined orbit using the Long March 4B launch vehicle, and the launch was a complete success. GAO-11-02 is an optical remote sensing satellite with a ground resolution of up to sub-metre, which is mainly used in such fields as land census, urban planning, land titling, road network design, crop yield estimation, disaster prevention and mitigation, and can provide information security for the construction of the “Belt and Road”.
On September 4, Shenzhen Maxphotonics Co., Ltd. (Chuangxin Laser) and Shandong Jinan Bodor Laser Co. reported that the 40kW multimode continuous laser sets the record of the highest power of the same kind of industrial laser cutting, equipped with a single module 6kW also simultaneously break the highest record of the domestic industrial utility single mode. https://play.yunxi.tv/livestream/flash?id=e757e5ed77e143e594280206f72e9558#/
