Quantum algorithmic differentiation

In this work we present an algorithm to perform algorithmic differentiation in the context of quantum computing. We two versions algorithm, one which is fully and employees a classical step (hybrid approach). Since implementation elementary functions already possible on computers, scheme that propose can be easily applied. Moreover, since some steps (such as CNOT operator) (or will be) faster computer than one, our procedure may ultimately emonstrate has advantage relative its counterpart.
