Abstract
To develop large-scale fault-tolerant quantum computers, implementation technologies are required to meet extremely strict conditions.Basic research targeting such technologies is currently being conducted worldwide, and theoretical research can also make a relevant contribution.In this article, we introduce several theoretical research studies for deriving the maximum power of quantum computers with limited resources and/or restricted functions due to difficulties in physical implementation.
