Self powered robotic fish operating in Mariana Trench at a depth of 10,900m.
Silicone based. No/little metal. Bio-mimic without a traditional power plant. Imagine how hard it would be for a submarine to track them down.

Now imagine if they could scale up to dolphin/ray sized with speed that is similar to a submarine in silent mode (i.e. battery powered). With AI it would be an stealthy way to patrol waterways and track adversary submarines. Add a small shaped explosive, and it can attach itself to a submarine and blow itself up.

The difficulty would be power storage and recharging. There are solutions for that too however. For example, having a mothership disguised as fishing boat etc that serves as a charging station.

From what I have beard this robot was mostly a "proof of concept" to show if all these ideas were working correctly.

It seems as a success so now they have to move from proof of concept to developing more tech, increasing capabilities and even commercialise it. Should take 10 years for the research team and maybe 7-8 years for the PLA to start experimenting with it

Do submarine track/detect EM radiation? Because submarine will detect those.

Huawei reveals royalty rates for 5G tech​

Huawei Technologies Co disclosed on Tuesday the royalty rates for the use of its 5G technologies in smartphones, as the Chinese tech giant aims to increase transparency about its intellectual property.

The move came as Huawei has become one of the world's largest patent holders through sustained investment in innovation. By the end of 2020, Huawei held over 100,000 active patents worldwide.

Jason Ding, head of Huawei's intellectual property rights department, said for every multimode 5G smartphone that uses Huawei's 5G technologies, the company will get up to $2.5 in royalties.

Huawei estimated it will receive about $1.2 billion to $1.3 billion in revenue from patent licensing between 2019 and 2021.

Huawei's total revenue in 2019 reached 858.8 billion yuan ($132.2 billion).

According to Ding, Huawei has been the largest technical contributor to 5G standards and follows fair, reasonable and nondiscriminatory principles in patent licensing.

He added that the company hopes the royalty rate it announced on Tuesday will increase 5G adoption by giving 5G implementers a more transparent cost structure that will inform their investment decisions.

Francis Gurry, former director general of the World Intellectual Property Organization, said, "In releasing its license fee structure for 5G standard essential patents, Huawei is promoting the widespread adoption and use of standards designed to ensure interoperability, reliability and transparent competition, while at the same time providing a fair return for investment in R&D."

From 2010 to 2019, Huawei spent about $90 billion on R&D, according to a white paper on innovation and intellectual property the company issued on Tuesday.

Song Liuping, chief legal officer of Huawei, said: "We want to show the history of our innovation over the past 30 years and our long-term commitment to respecting, protecting and contributing to IP. With this white paper, we want you to better understand how Huawei has become what it is today."

The move also came as Huawei faces a string of restrictions from the US government, affecting its smartphone businesses.

Song said Huawei holds over 10,000 patents in the US, which bring value to many US companies. As a major contributor of patents essential to 5G standards, the company is willing to share these technologies with the world.

2. The Chinese experiment is not reprogrammable. So basically all the work from research to design to implementation was hard-coded from the start. So if you want to do something else with this quantum "computer" you cant because the experiment was made specifically to solve one algorithm.
As far as I know, all the current implementations are hard-coded for a specific computation. You have to re-wire the hardware to do a different job.

There are more US entities than China making announcements of quantum computing experiments. But I think the latest Chinese announcement has the highest Qubit count, similar in conventional computers CPU bit width, 32bits, 64bits.

P.S. I am not stating that China is ahead of US in quantum computers. But because of the natural of quantum computer development especially the debatable benchmark of realizing quantum computing, it is not easy to make a conclusion according to the announcement.

Is China the only country doing research in this field?

China makes major breakthrough in converting solar energy into liquid fuel​

China has made a breakthrough in converting solar energy into liquid fuels, with a project producing a liquid product with 99.5% methanol content, according to

.
The success, which was achieved in January 2020 and recently received CCTV coverage, is the first attempt to synthesize direct solar fuels on a global scale.
The project, if operating at full capacity, could produce 1,500 tons of methanol per year, consume 2,000 tons of CO2 and generate 15 million kWh of electricity using solar energy, the report said, citing experts.
China's annual methanol production capacity is about 80 million tons, and in 2019, China accounted for 29 percent of global CO2 emissions. If solar fuel is used to synthesize methanol, hundreds of millions of tons of CO2 can be reduced each year.
The research work on "artificial photosynthesis for solar fuels production" started in 2001: the first step is to turn light into energy in the form of photovoltaic power, the second step is to electrolyze water to make hydrogen, and the third step is to hydrogenate carbon dioxide to make methanol.

Researchers have calculated that each ton of hydrogen produced by electrolysis of water is equivalent to 33,000 kWh of electricity stored. Converting electrical energy into chemical energy is the most efficient chemical energy storage reaction.
If methanol is used as a fuel instead of coal, PM2.5 emissions will be reduced by more than 80% and NOx by more than 90%.
That is interesting. Basically it is replicating the natural process of crude oil.
In nature, solar energy + CO2 - photosynthesis -> carbohydrate -> plantation -> animal -> dead corpse + high pressure + temperature + millions of years -> crude oil -> hydrocarbon fuel.
In this process, solar energy -> electricity -water-> hydrogen -CO2-> hydrocarbon fuel.
