Abstract

Towards the full-fledged quantum computing, what do we need? Obviously, the first thing we need is a (many-body) quantum system, which is reasonably isolated from its environment in order to reduce the unwanted effect of noise, and the second might be a good technique to fully control it. Although we would also need a well-designed quantum code for information processing for fault-tolerant computation, from a physical point of view, the primary requisites are a system and a full control for it. Designing and fabricating a controllable quantum system is a hard work in the first place, however, we shall focus on the subsequent steps that cannot be skipped and are highly nontrivial.
