Dec 9 at 4:18 | comment | added | akkapi | Note that the paper of Shukla & Vedula (arxiv.org/abs/2306.11747) achieves a superposition of computational basis states $| k_1 \rangle , \ldots, | k_M \rangle$ if $k_j = j - 1$, meaning only for the initial segment $[0, M - 1] \subset [0, 2^n - 1]$. The improvement over just Hadamard gates is that $M$ need not be a power of $2$ here. This doesn't quite answer the question of the OP, since there the subset can be arbitrary. Interestingly, this was recently overlooked elsewhere (see journals.aps.org/pra/pdf/10.1103/PhysRevA.110.056401) attempting to use Shukla-Vedula. | |
