China's new breakthrough in science and technology: a leap in computing power
Quantum Computation New Highlands
In this digital age, the importance of computing power is self-evident. It is like the engine of modern society, driving scientific and technological innovation and economic development. Recently, China has made an impressive breakthrough in the field of quantum computing power, leading a new highland of computing power.
The Beijing Institute of Quantum Information Science, together with the Institute of Physics of the Chinese Academy of Sciences and Tsinghua University, has successfully developed a "large-scale quantum cloud computing power cluster". This cluster integrates 5 100-bit quantum chips, with a total of 590 physical bits, and the comprehensive indicators are close to the forefront of the world. It uses an innovative tunable coupling architecture and process improvements to dramatically improve the performance of quantum chips. The highest two-bit gate fidelity is an astonishing 99%, and the average is over 97%. This means that the accuracy and reliability of quantum computing have been improved like never before, providing powerful computing power for solving complex scientific and engineering problems.
Quantum computing, known as the "sub-technological revolution", uses the strange phenomena of quantum mechanics, such as quantum superposition and quantum entanglement, to perform specific computing tasks. Compared with classical computers, quantum computers have a huge speedup advantage when dealing with certain problems, such as numerical simulations, optimization problems, and large number factorization. The advent of large-scale quantum cloud computing clusters marks a major breakthrough in this cutting-edge technology field in China, laying a solid foundation for future quantum computing applications.
A new era of optoelectronic intelligent chips
In addition to the leap in quantum computing power, China has also made remarkable achievements in the field of optoelectronic computing. Fang Lu's research group in the Department of Electronic Engineering at Tsinghua University has developed an AI optical chip called "Taiji", which has a general intelligent computing capacity of up to 160 TOPS/W. This figure is staggering, because it means that the "Tai Chi" chip is about 1,000 times faster than traditional electronic chips.
Optoelectronic computing is an emerging technology that uses photons instead of electrons for computing. Compared with electronic computing, it has higher bandwidth, lower power consumption, and stronger parallel processing capabilities. The breakthrough performance of the "Taiji" chip is due to its use of large-scale interference-diffraction heterogeneous integration technology. This technology highly integrates an optical waveguide and a nanoantenna array on a single chip, enabling efficient conversion and processing of optoelectronic signals.
Optoelectronic computing is considered to be an important development direction of computing in the future, especially in the fields of artificial intelligence and big data processing. The advent of the "Taiji" chip not only demonstrates China's scientific and technological strength in this field, but also explores a new technical path for high-performance computing power.
A new highland of computing power, and the strength of science and technology is highlighted
Whether it is the "large-scale quantum cloud computing power cluster" or the "Taiji" AI optical chip, these two major achievements demonstrate China's scientific and technological strength in the field of computing power. They provide a new technical route for high-performance computing power, and are expected to promote the development of cutting-edge technologies such as quantum computing and artificial intelligence.
In the current competition in science and technology, computing power is becoming an important embodiment of a country's comprehensive national strength. Having strong computing power not only means the ability of scientific research and innovation, but also represents the right to speak in key fields. China is speeding up the breakthrough of "stuck neck" technology and challenging the leading position of international science and technology.
The achievement of these two achievements is the significant progress that China has made in this process. They mark China's scientific and technological strength in frontier fields such as quantum computing and optoelectronic computing, and lay a solid foundation for future scientific and technological innovation. I believe that in the near future, we will definitely be able to see more new achievements in China's science and technology, leading a new highland of computing power and technology.
