Fault-Tolerant Measurement-Based Quantum Computing with Continuous-Variable Cluster States

Summary

Establishes that finitely squeezed continuous-variable cluster states can support fault-tolerant measurement-based quantum computation when continuous-variable error correction is concatenated with a qubit code. The original conservative analysis gives a 20.5 dB initial-squeezing threshold and identifies finite-squeezing displacement noise as the central fault-tolerance constraint.
