Web8 de fev. de 2024 · The question asks about "arbitrary functions" and "any problem"; the accepted answer talks only about continuous functions. The answer to the question as stated now, in both versions, is clearly "no". Some fun counterexamples: "Any problem" includes Turing's Entscheidungsproblem, which is famously unsolvable. http://en.negapedia.org/articles/Hidden_linear_function_problem

WebScience 362 (6412) pp. 308-311, 2024. The quantum circuit solves the 2D Hidden Linear Function problem using a *constant* depth circuit. Classically, we need a circuit whose depth scales *logarithmically* with the number of bits that the function acts on. Note that the quantum circuit implements a non-oracular version of the Bernstein-Vazirani ... The hidden linear function problem, is a search problem that generalizes the Bernstein–Vazirani problem. In the Bernstein–Vazirani problem, the hidden function is implicitly specified in an oracle; while in the 2D hidden linear function problem (2D HLF), the hidden function is explicitly specified by a matrix and a binary vector. 2D HLF can be solved exactly by a constant-depth quantum circuit restricted to a 2-dimensional grid of qubits using bounded fan-in gates but can't be solved by an…
