In order to realize a Quantum CPU some schemes for executing fundamental mathematical tasks are needed. In this paper we present some quantum circuits which, using elementary arithmetic operations, allow an approximated calculation of continuous functions. Furthermore, we give an explicit example of our procedure applied to the exponential function.
