We study the diffraction of two maximally entangled qubits encoded into spatial modes of light with orbital angular momenta±ℏl 0, on angular apertures. Exploiting the uncertainty relation between angular position and momentum, we quantify the diffraction-induced entanglement loss, for different l 0, as a function of the angular uncertainty Δϕ induced by the apertures. We demonstrate that the degradation of entanglement follows a universal law parametrised by the product l 0 Δϕ alone.
