Abstract
To reach quantum supremacy, quantum computers need >50 logical qubits with <; mv accurate biasing, GHz-range signal handling, and μs readout of thousands of physical qubits at sub-Kelvin temperatures. Silicon-based qubits are a promising approach to scale the qubit number owing to their low footprint (100nm) and gaining from the CMOS industrial background to reach maturity [1].
Moreover, the quantum silicon choice allows the IC community to integrate large-scale qubit-control electronics directly nearby the quantum silicon core, thus drastically reducing the wire-connection number and qubit-addressing fanout, meanwhile increasing the operation bandwidth for error correction and the spin-readout sensitivity.
