Spatially Dense, Continuous-Variable Quantum Computing with Solid State Spin Nonlinearities
A preprint on arXiv proposes a continuous-variable quantum computing architecture that uses solid-state spin systems as optical nonlinearities. The approach targets spatially dense operation by embedding spin nonlinearities for CV quantum information processing. The work appears on arXiv quant-ph.

This could enable chip-scale continuous-variable cluster state generation using solid-state spin arrays as deterministic nonlinearities within two years.
If the proposed solid-state spin nonlinearities can be integrated at high spatial density, they would provide the missing strong nonlinear element for CV photonic platforms, allowing compact generation and manipulation of entangled CV states. This path is credible but depends on experimental demonstration of the nonlinearity in a CV setting.
