Recently, China has made two major breakthroughs in the field of semiconductor chips. First of all, the world's first 28nm embedded RRAM image quality adjustment chip has achieved mass production. Secondly, the Hong Kong Polytechnic University has successfully developed the world's first 16-bit qubit semiconductor microprocessor chip.
Mass production of the world's first 28nm embedded RRAM image quality adjustment chip
According to the official account of "Beijing Yizhuang", China's semiconductor company Xianxin Technology has cooperated with domestic scientific research institutes to successfully develop and mass-produce the world's first 28nm embedded RRAM (resistive random access memory) image quality adjustment chip. The chip has been applied to high-end Mini LED TV products of well-known domestic brands.
The 28nm display chip adopts the "digital chip + embedded RRAM" technology scheme, which significantly reduces the cost of external memory and improves the read speed of compensation parameters compared with the current mainstream "TCON+ external FLASH memory" scheme in the industry. The chip integrates RRAM IP directly on the 28nm process node, bringing advantages in cost, size, and efficiency.
It is worth noting that this chip is not only the first self-developed 28nm display chip in China, but also the world's first commercial image quality adjustment chip using 28nm embedded RRAM IP, with completely independent intellectual property rights. The built-in RRAM memory module and core RRAM IP technology of the chip are derived from the achievements of scientific research institutes, and the image quality adjustment algorithm is independently developed by Xianxin Technology.

The world's first 16-bit qubit semiconductor microprocessor chip was successfully developed
At the same time, the research team of the Hong Kong Polytechnic University has successfully developed the world's first 16-bit qubit semiconductor microprocessor chip, providing a new solution for simulating the vibrational spectra of complex molecules.
Using a linear photonic network and a compressed vacuum quantum light source, the team successfully simulated molecular vibrational spectra and integrated the 16-bit quantum microprocessor into a single chip. In addition, the team has developed a complete system, including a quantum photonic microprocessor chip for photoelectric thermal packaging, a control module, driver software, a user interface, and a programmable quantum algorithm. This quantum computing system can be widely used in different computing models.
The quantum microprocessor is capable of handling complex tasks, such as simulating large protein structures or optimizing molecular reactions faster and more accurately. According to the research team, this method breaks through the traditional limitations, is expected to achieve early practical application of molecular simulation, and brings significant computational acceleration in the field of quantum chemistry.
The research and development has been supported by many well-known universities at home and abroad, including Nanyang Technological University, City University of Hong Kong, Beijing Institute of Technology, Southern University of Science and Technology, Institute of Microelectronics, Chinese Academy of Sciences, and Chalmers University of Technology, Sweden.
