What kind of processing and manufacturing can a steel billet go through to support the weight of hundreds of tons of large aircraft?
Forging, an ancient and important metalworking process. Through it, the famous sword was forged. Through it, the muscles and bones are strengthened. Between deformation and recrystallization, the structure and properties of the metal are changed, which promotes the qualitative improvement of the billet.
And today's China is also undergoing a transformation of productive forces like forging.
In the process of tempering, technological revolutionary breakthroughs, deep industrial transformation, and innovative allocation of production factors. Science and technology leading, innovation driven. New industries, new models, and new kinetic energy are constantly emerging, and new quality productivity is accelerating the formation of forging.
200 seconds = 10,000 years
What kind of superpowers do quantum computers have?
Zhang Hui, China's first Ph.D. in semiconductor quantum computing, and their company's self-developed third-generation quantum computer is called "Origin Wukong". Its powerful parallel processing capability has a wide range of application prospects in materials science, drug discovery, AI and other fields.
Superposition and entanglement of qubits are the two core features of quantum computing, and the higher the number of qubits, the stronger the computing power of the quantum computer.
Zhang Hui, general manager of Origin Quantum Computing Technology (Hefei) Co., Ltd., said that in 2019, Google used a 53-bit quantum computer to run in 200 seconds, and a traditional and mature supercomputer would run for 10,000 years.
Quantum computers are fast at computing and can solve specific problems quickly compared to classical computers, but they can't solve all of them. Therefore, Zhang Hui and others proposed a new method of "quantitative super-integration".
It is not only the integration of computing technology, but also the deep integration of regional collaborative innovation and development. In more than a year, quantitative hyper-convergence has achieved good results in weather forecasting, new materials, and artificial intelligence.
From quadriplegia to "mind" control
Brain-computer interface surgery in China is a boon for patients

In 2009, Lao Yang suffered a car accident, suffered cervical spine injuries, quadriplegia, and was completely unable to take care of himself for 15 years. In October last year, Lao Yang accepted the first clinical implantation of wireless minimally invasive brain-computer interface in mainland China with the participation of Professor Hong Bo's team at Tsinghua University.
After two coin-sized brain-computer interface processors were implanted into Lao Yang's skull, the machine collected intracranial nerve signals in the sensorimotor brain area, and then executed the relevant commands of the brain through the machine, helping Lao Yang re-realize life skills such as grasping through his mind.
Hong Bo was pleased with the changes in Lao Yang, he and his team began to study brain-computer interfaces in 2013, and under the pressure of simultaneous research and development by multiple domestic and foreign scientific research teams during the same period, Hong Bo and his team resolutely moved forward and achieved a breakthrough.
Today, brain-computer interface devices have moved out of the lab and into mass production.
In Shanghai's 10,000-level purification production workshop, it can produce 1,000 sets of brain-computer interface implants per year. In the future, the production capacity will continue to expand.
Spaceborne Hydrogen Clock - the "Heart" of Beidou Navigation Satellite
It takes 10 million years to make an error of 1 second
Today, after 30 years of scientific research and the joint efforts of several generations of Chinese astronauts, the mainland has successfully launched 58 Beidou navigation satellites, built a high-precision global satellite navigation system, and become one of the four major suppliers recognized by the United Nations Satellite Navigation Committee. BDS-3 pioneered the world's first phased array inter-satellite link technology to achieve one-star communication and one-star communication.
The high accuracy of the Beidou navigation system is one of its greatest advantages. The accuracy of the navigation system depends to a large extent on a key core component - the spaceborne atomic clock, which is the "heart" of the satellite navigation system, and was also a "heart disease". As early as 1972, the Shanghai Astronomical Observatory of the Chinese Academy of Sciences developed the mainland's first hydrogen atomic clock, but it weighed more than 100 kilograms and could not be used on satellites.
Shuai Tao, researcher at the Shanghai Astronomical Observatory of the Chinese Academy of Sciences and leader of the spaceborne hydrogen clock research group: Beidou-3 has a global network, and at this time, the requirements for the atomic clock on our satellite are higher, including frequency stability and drift rate, so we must overcome the stability index.
After long-term scientific research, the volume of the spaceborne hydrogen clock is shrinking, but the accuracy is constantly improving, and the error is only 1 second in 10 million years.
"Build well in the sky and use it well on the ground" is the goal of the Beidou system. Today, the total output value of mainland satellite navigation and location services exceeds 500 billion yuan, and the Beidou system has served users in more than 200 countries and regions.
The rapid development of cutting-edge technology has turned the science fiction ideas of the past into a reality within reach. With the strong driving force of scientific and technological innovation, the productive forces are moving towards a higher level of advanced form, and the continuous cultivation and development of new quality productive forces is strongly promoting the steady progress of China's economic giant ship on the channel of high-quality development.
China Central Radio and Television Financial Program Center micro-documentary "New Quality Productivity Forging" has a total of five episodes, namely "Promoting Quality with New", "Industrial Renewal", "Seeking Innovation from Green", "Innovation Ecology" and "Empowering the Future", which will be broadcast on the financial channel from May 1 to 5 at 9:45 a.m.
