Nonuniform code concatenation for universal fault-tolerant quantum computing
Nonuniform code concatenation for universal fault-tolerant quantum computing
Using transversal gates is a straightforward and efficient technique for fault-tolerant quantum computing. Since transversal gates alone cannot be computationally universal, they must be combined with other approaches such as magic state distillation, code switching, or code concatenation to achieve universality. In this paper we propose an alternative approach for …
