Hidden linear function problem

WebThe problem is to find such a vector z (which may be non-unique). This problem can be viewed as an non-oracular version of the well-known Bernstein-Vazirani problem [17], where the goal is to learn a hidden linear function specified by an oracle. In our case there is no oracle and the linear function is hidden inside the quadratic WebAbstract Recently, Bravyi, Gosset, and Konig (Science, 2024) exhibited a search problem called the 2D Hidden Linear Function (2D HLF) problem that can be solved exactly by a constant-depth quantum circuit using bounded fan-in gates (or QNC0circuits), but cannot be solved by any constant-depth classicalcircuit usingbounded fan-in AND, OR, and NOT …
