我们研究了如何连接不同的无退相干子空间（dfs）来实现可扩展的通用容错量子计算。基于可调的$XXZ$相互作用，我们提出了一种可扩展量子计算机的架构，该架构可以通过仅操纵单一类型的参数来容错执行通用量子计算。通过使用无交互子空间的概念，我们消除了调整逻辑量子比特之间耦合的需要，这进一步降低了实现量子计算的技术难度。
We investigate how to concatenate different decoherence-free subspaces (DFSs) 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 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.
