Abstract
In this brief report we show the new Bell-Clauser-Horne inequality for two entangled three dimensional quantum systems (so called qutrits). This inequality is violated by a maximally entangled state of two qutrits observed via symmetric three input and three output port beamsplitter only if the amount of noise in the system equals 11-63 2≈ 0.308. This is in perfect agreement with the previous numerical calculations presented in Kaszlikowski et. al. Phys. Rev. Lett. 85, 4418 (2000).
