| contents | One-way quantum computation is a promising approach to achieving universal, scalable, and fault-tolerant quantum computation. However, a main challenge lies in the creation of universal, scalable three-dimensional cluster states. Here, an experimental scheme is proposed for building large-scale canonical three-dimensional cubic cluster states, which are compatible with the majority of qubit error-correcting codes, using the spatiospectral modes of an optical parametric oscillator. Combining with Gottesman-Kitaev-Preskill states, one-way fault-tolerant optical quantum computation can be achieved with a lower fault-tolerant squeezing threshold. Our scheme drastically simplify experimental configurations, paving the way for compact realizations of one-way fault-tolerant optical quantum computation. |
