Chengdu Zhongwei Daxin Technology Co., Ltd. (hereinafter referred to as "Zhongwei Daxin") launched
a new "Shushan" series of low-temperature CMOS quantum measurement and control chipset for high-fidelity quantum gate control and parallel fast quantum state reading of large-scale quantum bit arrays .
As a domestic start-up with leading technology in the field of quantum measurement and control, Micro-Daxin recently launched
a new "Shushan" series of 2 8 nm low-temperature CMOS quantum measurement and control chipsets , including a total of three chips: "
Gongga" K onka superconducting qubit control Chips ,
" Emei" Emei superconducting qubit reading chip and "
Xiling " Xiling silicon-based qubit control chip . In response to the current domestic and foreign quantum chip requirements for high fidelity, low noise, high flexibility and low power consumption, this chipset has been adaptively designed to significantly reduce the interconnection complexity, cost and drift of current quantum measurement and control systems. Among them, the "Xiling" Xiling chip was jointly developed with the University of Electronic Science and Technology of China. It has been accepted by
the International Solid State Circuit Conference I SSCC 2025 and will have an on-site technology demonstration in San Francisco in February 2025 .
Konka: 28nm Cryo-CMOS superconducting quantum bit manipulation chip SoC
The Konka chip is designed based on the standard 28nm CMOS process, with a chip area of 2mm×3mm, and can work in the 4K temperature range. It contains two quantum control channels on the chip to realize dual quantum gate operation. Each control channel contains a 4~8GHz high-fidelity microwave pulse sequence generation XY channel and a high-precision gate pulse bias Z channel.
Emei: Cryo-CMOS frequency division multiplexing dispersion quantum state reading chip SoC
Emei is a 28nm low-temperature CMOS superconducting quantum bit reading chip SoC with a chip area of 2mm×3mm. It can realize parallel frequency division multiplexing FDM quantum state reading of two superconducting quantum bits in the 5.5~8 GHz frequency band. Figure 8 shows the system block diagram of Emei. The chip contains a frequency division multiplexing microwave pulse excitation TX channel, a high linearity low noise mixer pre-RX channel, and matching analog baseband AD/DA and on-chip quantum state demodulation digital signal processing module.
Xiling: Cryo-CMOS high-precision silicon-based quantum bit manipulation chip Soc
Xiling,
jointly developed with the University of Electronic Science and Technology of China, is a 65nm low-temperature CMOS high-precision silicon-based quantum bit manipulation chip. It has achieved high-precision manipulation of silicon-based single electron transistor devices at 60mK. The work, titled "Xiling: Cryo-CMOS 18-bit Dual-DAC Manipulator with 4.6μV Precision and 4.1nV/ Hz 0.5 Noise Co-integrated with the Single Electron Transistor at 60mK", was
accepted by the International Solid-State Circuits Conference (ISSCC 2025), the top conference in the field of integrated circuit design.
