Both Leica Q and Sony A68 have 24.0 MP resolution sensors but Leica Q's sensor is Full frame (36 x 24 mm ) and Sony A68's sensor is APS-C (23.5 x 15.6 mm ).
Since Leica Q's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Sony A68.
Below you can see the Q Typ 116 and A68 sensor size comparison.
As seen above, Leica Q has a 2.4x Larger sensor area than Sony A68. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
