Abstract: We predict quantized Imbert-Fedorov, Goos-H\"anchen, and photonic spin Hall shifts for light beams impinging on a graphene-on-substrate system in an external magnetic field. In the quantum Hall regime, the Imbert-Fedorov and photonic spin Hall shifts are quantized in integer multiples of the fine structure constant $\ensuremath{\alpha}$, while the Goos-H\"anchen ones in multiples of ${\ensuremath{\alpha}}^{2}$. We investigate the influence on these shifts of magnetic field, temperature, and material dispersion and dissipation. An experimental demonstration of quantized beam shifts could be achieved at terahertz frequencies for moderate values of the magnetic field.
