The immense scalability of continuous-variable cluster states motivates their study as a platform for quantum computing, with fault tolerance possible given sufficient squeezing and appropriately encoded qubits [Menicucci, PRL 112, 120504 (2014)]. Here, we expand the scope of that result by showing that additional anti-squeezing has no effect on the fault-tolerance threshold, removing the purity requirement for experimental continuous-variable cluster-state quantum computing. We emphasize that…

All-Gaussian Universality and Fault Tolerance with the Gottesman-Kitaev-Preskill Code.
It is shown that applying GKP error correction to Gaussian input states, such as vacuum, produces distillable magic states, achieving universality without additional non-Gaussian elements.

Cluster States from Gaussian States: Essential Diagnostic Tools for Continuous-Variable One-Way Quantum Computing
By a detailed analysis of the structure of Gaussian states, an algorithm is derived that reveals hidden entanglement in an arbitrary Gaussian state and optimizes its use for one-way quantum computing.
Are all Gaussian states also cluster states? Detecting hidden continuous-variable entanglement
It is shown here that Gaussian states can present hidden entanglement, which is not captured by the corresponding cluster state graph and therefore invalidates this graph.
Architecture and noise analysis of continuous-variable quantum gates using two-dimensional cluster states
A complete measurement-based quantum computing architecture for the implementation of a universal set of gates on the recently generated two-dimensional cluster states is proposed and it is found that, although they all allow for universal computation, the quad-rail lattice cluster state performs better than the other three states which all exhibit similar performance.
