| Outline of Final Research Achievements |
In this project, we proposed novel schemes for scalable quantum information processing and investigated their experimental feasibility. Specifically, we classify physical systems for quantum information processing into distributed systems with modular scalability and bulk systems with monolithic scalability. Then, we constructed schemes for scalable and fault-tolerant quantum information processing for each type of the physical systems. Especially, we show that in a bulk system we can realize a long-time quantum coherence by using quantum error correction with global control and dissipative feedback without any selective addressing of each individual particle in the system. We performed a feasibility study for an experimental realization with a nuclear-electron spin system and clarified experimental requirements.
