    • This "obvious" result has been claimed before though we have been unable to find a constructive proof of its universality in the existing literature. In, a partial result similar to Eq. 2 was stated, but a linear search protocol was implied.

    • Measurement of the probe qubit at each stage of the protocol partially "collapses" the state of the system. In principle, we can retain the ancilla qubits and perform unitary evolutions between later qubits and the system which are controlled by the states of all previously coupled ancilla, hence making the procedure reversible in the absence of a final measurement collapse.

    • If all outcomes are equally likely the average number of operations is half the maximum; a priori knowledge of probabilities may reduce the average number of operations by selecting the more likely outcomes first to be measured.
