Scalable Addressing Circuits for a Surface Code Quantum Computer in Silicon

Abstract

Practical quantum computers require coordinated operation on a large number of qubits $(\sim 10^{4})$, posing significant implementation challenges. In this paper, we summarize our recent work on scalable CMOS circuits to route control signals in a silicon MOS quantum dot spin qubit. We also present a cryogenic compact model enabling circuit design and simulation at cryogenic temperatures. The proposed design is an important step toward implementation of scalable solid-state quantum processors.
