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

Overview of the operation and calibration of an 8-dot device.

Quantum engineering pioneer Diraq has announced a validation milestone in silicon-based solid-state quantum architectures with the publication of its peer-reviewed paper, “Eight-Qubit Operation of a 300 mm SiMOS Foundry-Fabricated Device,” in Nature Communications. In direct collaboration with European nanoelectronics hub imec, the research team successfully scaled a linear array of silicon spin qubits from a two-qubit unit cell to an integrated eight-qubit processor. Crucially, the multi-qubit device was manufactured entirely within a commercial, industry-standard 300 mm Silicon Metal-Oxide-Semiconductor (SiMOS) foundry line, demonstrating that highly uniform, qubit-grade quantum dot configurations can be replicated at volume without sacrificing fundamental quantum coherence or gate operational control.
