Gisin's theorem for two d-dimensional systems based on the   Collins-Gisin-Linden-Masser-Popescu inequality
  In this Rapid Communication, we show analytically that all pure entangled states of two d-dimensional systems (qudits) violate the Collins-Gisin-Linden-Masser-Popoescu (CGLMP) inequality. Thus one has the Gisin's theorem for two qudits.
