We examine theoretically magnetic quantum oscillations like the de Haas--van Alphen and Subnikov--de Haas effects in vortex states in type-II superconductors. For a magnetic field {ital B} not very small compared with {ital H}{sub {ital c}3}({ital T}), the main effect of superconductivity is introduction of the extra quasiparticle scattering rate proportional to {vert bar}{Delta}{vert bar}{sup 2}, the square of the superconducting order parameter. Therefore the detectability of the magnetic quantum oscillation is determined from the condition that the extra Dingle temperature due to {vert bar}{Delta}{vert bar}{sup 2} is not too large. For example in a magnetic field {similar to}10 T, the superconducting transition temperature {ital T}{sub {ital c}} has to be less than 30 K in order to have a reasonable signal.
