High-Threshold Quantum Computing by Fusing One-Dimensional Cluster States

2023 · Physical Review Letters

We propose a measurement-based model for fault-tolerant quantum computation that can be realized with one-dimensional cluster states and fusion measurements only; basic resources that are readily available with scalable photonic hardware. Our simulations demonstrate high …

Mitigating errors in logical qubits

2024 · Communications Physics

Quantum error correcting codes can enable large quantum computations provided physical error rates are sufficiently low. We combine post-selection with surface code error correction through the use of exclusive decoders, which abort on decoding instances …
