  Quantum computing (QC) has already entered the industrial landscape and
several multinational corporations have initiated their own research efforts.
So far, many of these efforts have been focusing on superconducting qubits,
whose industrial progress is currently way ahead of all other qubit
implementations. This paper briefly reviews the progress made on the
silicon-based QC platform, which is highly promising to meet the scale-up
challenges by leveraging the semiconductor industry. We look at different types
of qubits, the advantages of silicon, and techniques for qubit manipulation in
the solid state. Finally, we discuss the possibility of co-integrating silicon
qubits with FET-based, cooled front-end electronics, and review the device
physics of MOSFETs at deep cryogenic temperatures.
