We present a scheme to improve the noise threshold for the fault-tolerant topological one-way computation with a constant overhead.
- Certain cluster states of finite size, say star clusters, are constructed with logical qubits through an efficient verification process to achieve high fidelity.
- Then, the star clusters are connected near-deterministically with verification to form a three-dimensional cluster state to implement the topological one-way computation.
- The necessary postselection for verification is localized within the star clusters, ensuring the salability of computation.
