Conic extensions of parameterized quantum circuits enable jumps from barren plateaus to fertile valleys via non-unitary operations and ancilla, reducing optimal jump selection to a generalized eigenvalue problem and improving QAOA sampling in simulations.
The size of the constructed ball Bi is adapted in each step i: The steeper the drop in expectation values, the smaller the radius becomes
