Exact Learning with Tunable Quantum Neural Networks and a Quantum Example Oracle

Abstract

In this paper, we study the tunable quantum neural network architecture in the quantum exact learning framework with access to a uniform quantum example oracle. We present an approach that uses amplitude amplification to correctly tune the network to the target concept. We applied our approach to the class of positive $k$-juntas and found that $O(n^2{2}^k)$ quantum examples are sufficient with experimental results seemingly showing that a tighter upper bound is possible.
