TL;DR: In this article, the authors review several strategies that are considered to address this crucial challenge in scaling quantum circuits based on electron spin qubits. But, the wiring and interconnect requirements for quantum circuits are completely different from those for classical circuits, as individual direct current, pulsed and in some cases microwave control signals need to be routed from external sources to every qubit.

TL;DR: The demonstration of ‘hot’ and universal quantum logic in a semiconductor platform paves the way for quantum integrated circuits that host both the quantum hardware and its control circuitry on the same chip, providing a scalable approach towards practical quantum information processing.

TL;DR: In this paper, a three-layer design is proposed to increase the number of qubits to the thousands or millions required for practical quantum information, based on shared control and a scalable number of lines.

TL;DR: In this article, a Fuchs-Sondheimer (FS) and Mayadas-Shatzkes (MS) model is extended to account for the large variation in the specific resistivity of different grain boundaries as well as distinct top and bottom surfaces with different scattering specularity.

TL;DR: A model based on spin-valley mixing is developed and it is found that Johnson noise and two-phonon processes limit relaxation at low and high temperature, respectively.
