We determined the two-photon absorption (2PA) of CdSe quantum dots (QD) with diameters of 3 to 4.5 nm, through measurement of 2PA cross sections and theoretical calculations. While the 2PA cross sections of the QDs are among the largest observed to date for a single material structure, they suffer compared to organic molecules due to the large molar mass of the QDs.  The 2PA cross section normalized to the molar mass for CdSe QDs reaches 1 GM/Da (1 GM = 10-50 cm4 s/molecule), whereas conjugated molecules reach much higher values up to 20 GM/Da but generally have lower photostability.
