Scalable Fault-Tolerant Quantum Computation in Decoherence-Free Subspaces
PHYSICAL REVIEW LETTERS, 2004 (7) 2: 010501-4，-0001，（）：
We investigate how to concatenate different decoherence-free subspaces to realize scalable universal fault-tolerant quantum computation. Based on tunable XXZ interactions, we present an architecture for scalable quantum computers which can fault-tolerantly perform universal quantum computation by manipulating only a single type of parameter. By using the concept of interaction-free subspaces, we eliminate the need to tune the couplings between logical qubits, which further reduces the technical difficulties for implementing quantum computation.
