Diraq and imec Demonstrate Eight-Qubit Linear Array Fabricated on 300 mm CMOS Silicon Foundries

Diraq, a quantum engineering pioneer, has achieved a significant milestone in silicon-based solid-state quantum architectures by demonstrating an eight-qubit linear array fabricated on 300 mm CMOS silicon foundries. This breakthrough was made possible through a direct collaboration with imec, a European nanoelectronics hub. The research team's findings were published in a peer-reviewed paper, "Eight-Qubit Operation of a 300 mm SiMOS Foundry-Fabricated Device," in Nature Communications¹. The successful operation and calibration of the eight-qubit device mark a crucial step forward in the development of scalable quantum computing technologies. By leveraging standard CMOS silicon manufacturing processes, Diraq and imec have paved the way for the mass production of quantum devices, potentially reducing costs and increasing accessibility. This advancement matters to quantum computing practitioners because it brings the industry closer to achieving reliable, large-scale quantum computing capabilities, which could revolutionize fields like cryptography and optimization.
