Publication number: 20240114805Abstract: A quantum device includes: a quantum chip, provided with an I/O port; and a superconducting substrate, provided with transmission lines on the superconducting substrate. Each of the transmission lines includes a first section and a second section that form an included angle, a bonding connection structure is formed between one end of the first section and the I/O port, a pad for connecting to a connector is formed at one end of the second section, and a distribution spacing between the first sections is smaller than a distribution spacing between the second sections. The second sections are distributed in a region away from the quantum chip. The first section connected to the 1/0 port via aluminum wire bonding can be wired at higher density. The size of the pad on a wiring spacing is reduced, and density of the transmission lines on the superconducting substrate is increased.Type: ApplicationFiled: December 8, 2023Publication date: April 4, 2024Applicant: ORIGIN QUANTUM COMPUTING TECHNOLOGY (HEFEI) CO., LTDInventors: Yongjie ZHAO, Ye LI, Xiaoguang WANG, Xiaochuan WANG

Publication number: 20240077626Abstract: A signal processing system and method for a radiation detector based on a metal oxide semiconductor (MOS) transistor are disclosed. The signal processing system includes a power supply generation module, an analog signal processing module, and a digital signal acquiring-processing module. The power supply generation module provides a novel power supply method, and converts a positive high voltage power supply into a negative high voltage power supply to supply power to a last dynode of a photomultiplier tube (PMT). The analog signal processing module converts a negative current pulse signal into a voltage difference signal. The digital signal acquiring-processing module acquires a signal of the analog signal processing module, and converts the signal into a digital signal for identification.Type: ApplicationFiled: January 4, 2023Publication date: March 7, 2024Inventors: Qiang Liu, Zhenhua Lin, Jinhan Wang, Kunliang Yao, Yudong Luo, Sheng Wu, Yongjie Wang, Jianzheng Gao, Ming Cui
