Simon is the second seed that Anderson has knocked out of the tournament in Indian Wells following the South African's surprise victory over David Ferrer in the second round.
He booked his place in the last eight with 6-3 1-6 6-4 triumph over the Frenchman in one hour and 48 minutes.
Anderson will face either Richard Gasquet or Tomas Berdych for a place in the semi-finals.
