Scaling silicon-based quantum computing using CMOS technology

As quantum processors grow in complexity, attention is moving to the scaling prospects of entire computing system, including classical support hardware. Recent results high-fidelity control individual spins silicon, combined with demonstrations that these qubits can be manufactured a similar fashion field-effect transistors, create an opportunity leverage know-how complementary metal–oxide–semiconductor (CMOS) industry address challenge at system level. Here we review silicon-based using CMOS technology. We consider concept which decompose into three distinct layers—the layer, quantum–classical interface and layer—and explore challenges involved their development, as well assembly architecture. Silicon offers enticing possibility all layers can, principle, technology, creating move from distributed systems integrated solutions. This Review examines based on silicon spin technology how different such computer could benefit
