The implementation of quantum information and communication which depended on ability of producing, transmitting and reconstructing known as qunits on pure state in three-dimensional space was investigated. The tomographic techiques and maximun-likelihood estimation method were used in reconstruction of qutrit. More than 2400 different projections were used for tomographic reconstruction. The three basic steps in quantum communication or computing protocol were implemented by orbital angular momentum (OAM).
