The entanglement loss of high-dimensional entangled orbital angular-momentum states in far-field diffraction by a circular aperture was studied theoretically. A general expression for high-dimensional entanglement decay is provided. The results show that the loss depends on both the parity and the magnitude of the orbital angular-momentum index, and it is not affected by a small misalignment error of the aperture.
