The size $l$ of this set is limited due to the computational costs required to run the method on classical processing units. We present a qubit-efficient variational quantum algorithm that implements a quantum version of local search with only $\\lceil \\log_2 l \\rceil$ qubits and, therefore, can potentially work with classically intractable neighborhood s","authors_text":"M.
