Abstract

Decoherence-free subspaces (DFS) are proposed to perform universal, fault-tolerant quantum computation. The system remains within the DFS throughout the entire implementation of a quantum gate. The universal computation on clusters of the four-qubit DFS encodes one logical qubit under spatially collective decoherence.
