Guys, one question -

Did the Chengdu Tianfu new Airport use architeural designs and ideas from Beijing Daxing International Airport.

Is there an attempt to recuperate, maybe, the investment made into commissioning architecture and ideas from Zaha Hadid Architects? I'm curious as the Tianfu design looks like someone cut the Daxing Star design through the middle and gave a gap.

Just plain old copying.

Disappointing if true. Airports are permanent assets that they will become landmarks for decades. Has the Gov not thought about that?

I am not asking about crazy designs but at the very least the airport should have its own aesthetic (ideally similar to the city/region)

Chinese technology giant Huawei is reportedly set to launch two satellites together with two Chinese partners in July this year, with aims including the verification of the 6G network technologies that the company has taken the lead in the research and development (R&D) around the world.

The satellite launch, with the cooperation of Chinese network operator China Mobile and a national space firm, which has no details unveiled, has great significance for China's core technologies such as networking and switching, according to a post on Friday by an independent digital blogger named Chang'an Shumajun, who claims having close relations with Huawei.

A Huawei PR told the Global Times on Saturday that he has not obtained such information so far.

China Mobile did not respond to the Global Times as of press time.

The satellite move is natural as Huawei pushes ahead its layout on 6G networks, which is 50 times faster than 5G, Ma Jihua, a senior tech industry analyst based in Beijing, told the Global Times on Saturday.

Compared with the construction of 5G networks that rely on base stations to transmit signals, 6G networks, conveying higher frequencies, need using satellite for communications instead of base stations where there will be low penetrability, Ma explained.

Huawei's rotating chairman Xu Zhijun announced at Huawei global analysts conference held earlier this month that the Chinese tech giant will launch its 6G networks in 2030, and it will release a 6G white paper soon to explain to the industry what 6G is.

Actually back in 2019, Huawei proposed its vision to launch more than 10,000 small satellites to provide 6G services covering the world, during a global 6G summit.

China has made the largest 5G footprint around the world and is likely further along into the 6G development with efforts from such bellwether as Huawei, whose 5G is already significantly ahead of its rivals, and has also taken the lead in 6G R&D despite the US' groundless crackdown on its chip supply.

The potential of 6G technologies is something that none government or firm could ignore despite the fact that it is still at the early R&D phase, according to Ma.

Satellite communications have been attached to increasing importance since last year with the proposal of "new infrastructure." "We need to know the constellation communication as the nation pushes forward is different from Huawei's 6G move although they both use satellites," Ma noted.

China's satellite constellation, as current projects Hongyun and Hongyan have been involved in, aims to enable broader online access for people and businesses in China's remote and poorer areas. While, the 6G satellite is more used for tests and providing data in popular urban areas, Ma added.

Late last year, China launched world's first 6G experiment satellite from the Taiyuan Satellite Launch Center in North China's Shanxi Province, marking a breakthrough in the exploration of terahertz space communication technologies in China's space field.

The satellite, carrying a terahertz satellite communication load, planned to establish a transceiver link on the satellite platform and carry out terahertz load tests.

The two terminal buildings will be constructed in the shape of the mythical sunbird, used as a logo for the city of Chengdu which has a history of some 3,000 years and represents the creativity and exploration of Sichuan people.

From a central hollow circular core, 6 arms will radiate outwards with both terminals mirroring the other...

Just to add on.

"Sichuan province’s planned new Chengdu Tianfu International Airport is being designed by the China Southwest Architectural Design & Research Institute Corp Ltd (CSWADI) in partnership with ADP Ingénierie."

ADPI and CSWADI actually beat out Daxing's architects, Zaha Hadid, in the international design competition for Chengdu Tianfu.

The starfish shape is popular because it efficiently maximizes aircraft gates while at the same time minimizes average walking distance for passengers from check-in to gate.

If you want to criticize, Qingdao Jiaodong is a more faithful imitation of Daxing.

The University of Science and Technology of China announced on the 25th that the research group of Li Chuanfeng and Zhou Zongquan recently successfully increased the optical storage time to 1 hour, which greatly refreshed the 1-minute world record set by the German team eight years ago, and is important to the realization of a quantum USB flash drive.
!!!

This research greatly prolongs the storage time and is therefore expected to give birth to a series of innovative applications.
For example, saving the light captured by two telescopes far apart and putting them together for "interference" processing can break through the size limitation of a single telescope and greatly improve the accuracy of observation.
This is huge for astronomy

Quantum USB flash drives are of great significance to the construction of a global quantum communication network.
Great achievement, and it seems that China is leading at this field.

Ok, same achievement but this time reported by SCMP which offers some other applications for this tech

A research team in China have trapped light in a piece of crystal for an hour, a breakthrough in information technology that could have important applications such as transporting sensitive data in hack-proof form.
The crystal could be kept in a device about the size of a suitcase, and transported. If someone opened the device without a key, the light – and the sensitive information it carried – would be destroyed
The technology would offer unprecedented security with the potential to “extend the communication distance to global scale”, said Professor Li Chuanfeng
OMG! This is HUGE! Wtf man this is very very big news

Despite its novelty, the crystal used in the Hefei experiment could be manufactured in bulk by China’s crystal suppliers, paving way for the mass application of the light storage technology, he said.
OMG x2!! This crystal is actually mass producable!

If they can increase the duration by at least an hour or more then this is gamechanging stuff.

This should be top level classified/national secret, why has China openly published this paper?

Beijing Daxing design is supposed to minimize the distance for travelers to walk to their boarding gates from the security areas. This design has become the new world standard. The Chengdu Tianfu is just as nice and impressive.
