我们提出了一种有效的方法来确定性地产生可扩展的光子簇态。这种方法涉及对耦合到光学腔的原子进行的幺正变换。它的运行成本与簇态量子比特的数量成线性关系，并且光子量子比特被编码，使得单量子比特的操作可以很容易地通过线性光学实现。由于簇态可以存储在原子中，然后转移到易于操作和测量的光子中，因此可以执行鲁棒的光学单向量子计算。因此，该方案有助于实现鲁棒的大规模光学单向量子计算。
We propose an efficient approach for deterministically generating scalable cluster states with photons. This approach involves unitary transformations performed on atoms coupled to optical cavities. Its operation cost scales linearly with the number of qubits in the cluster state, and photon qubits are encoded such that single-qubit operations can be easily implemented by using linear optics. Robust optical one-way quantum computation can be performed since cluster states can be stored in atoms and then transferred to photons that can be easily operated and measured. Therefore, this proposal could help in performing robust large-scale optical one-way quantum computation.
