We present a simulation of the quantum Zeno effect (QZE) on a quantum computer as an example of the relation between this effect and the bang-bang decoupling method in control theory. Although the true QZE can not be strictly implemented on a quantum computer where all the operations, except the final measurements, must be unitary ones, we can simulate it by coupling the system to a number of ancillas and replacing the projective measurements of the QZE by suitable unitary gates.
