  abstract = {The difficulty of copying an arbitrary quantum state is one of the basic rules governing the physics of quantum systems. Universal Quantum Copying Machine (UQCM) produces two identical copies whose quality is input-state independent. It is evident that the UQCM can be used effectively for the intrustion detection. We have used the isotrophic cloning to study the behavior of the coordinate ratios as a function of the intrusion parameters. As evidenced from this study, there is a strong correlation between the coordinate ratios and the fidelity. Thus, like the fidelity, the coordinate ratios can provide further information on the degree of intrusion. They are also helpful for designing quantum circuits.},
