The nondiffracting higher-order Bessel beams carry the orbital angular momentum (OAM). During free propagation, their transverse intensity profile remains nearly invariant in a range. The beam comprises the topological charge l helical phasefronts and carries an orbital angular momentum of lh per photon. The angular momentum number carried by the photon in each eigenmode is represented by l, and the eigenstates |l> can generate multidimensional quantum entangled states. A method of optical communication is presented that encodes information in two orthogonal orbital angular momentum states based on higher-order Bessel beams. Each photon carries OAM states of information, which can increase the key generation rate of the protocol, and offer a quantum solution for increase of the optical communication distance.
