The resonant (qu)modes of a single optical cavity form a quite large number of well-defined quantum optical fields. When that cavity contains a nonlinear material, i.e., a multiphoton emitter, it becomes an exotic light source, e.g. an optical parametric oscillator (OPO), which, as we have shown, can be made to emit large numbers of qumodes in multimode-squeezed, multipartite- entangled quantum states. We have also shown that said multipartite entanglement can (easily) be made to be of the cluster-state type, which is a major component of a quantum computer. The other major component of a quantum computer would be quantum fault tolerance which, in a nutshell, requires that either some states or gates include some nonpositivity in their Wigner functions. I will present my group's progress on the parallel fronts of massively scalable Gaussian entanglement and non-Gaussian quantum state tomography and engineering toward quantum error correction.
