Abstract
Quantum learning is learning properties of unknown quantum objects (states and operations) by connecting the objects to a quantum computer. Fully-quantum learning is directly calculating a specific property of a quantum object by a quantum computer without extracting unnecessary classical information about the quantum objects and formalized by a higher-order quantum transformation (a map of a map). We first present a higher-order quantum algorithm that optimally compares two unknown unitary operations with multiple calls of each unitary operation [1]. Then, we present another higher-order quantum algorithm to learn and apply the inverse of an unknown unitary operation with finite calls of the unitary operation [2].
