摘要：
In this paper we present the results of numerical calculations about the minimal value of detection efficiency for violating the Clauser-Horne inequality for qutrits. Our results show how the use of nonmaximally entangled states greatly improves this limit with respect to maximally entangled ones. A stronger resistance to noise is also found.
