Consider the phaseless stabilizer StateHSP and stabilizer state cloning tasks, for which the paper establishes worst-case lower bounds. Average-case extension conjecture. The worst…

Let $M$ denote the number of output clones, and let $F_{\mathrm{clon}}[N\to M]$ and $F_{\mathrm{est}}[N\to M]$ be, respectively, the global fidelities of quantum cloning and measur…
