Let $\mathcal{A}^{Q}:\mathbb{C}^{d^n\times d^n}\rightarrow\mathbb{R}^{KQ}$ be the linear map induced by $Q$ random unitary matrices, and let $\overline{\mathbb{X}}_{\overline{r}}$…

Random sampling conjecture. The orbit of a generic signal $x\in\mathbb{C}^N$ can be recovered from $O(N)$ random samples of its high-order spectra with high probability.
