An improved lower bound on query complexity for quantum PAC learning

In this paper, we study the quantum PAC learning model, offering an improved lower bound on the query complexity. For a concept class with VC dimension d, the lower bound is for ? accuracy and 1−δ confidence, where e can be an arbitrarily small positive number. The lower bound is very close to the best lower bound known on query complexity for the classical PAC learning model, which is .
