Qubit and qPCR quantify different properties of library. Qubit quantifies dsDNA regardless of adapter presence in fragment termini while qPCR quantifies the fragments flanked by adapters that are amplifiable. The quantity measured by these methods will be closer to each other if all fragments were double stranded and flanked by adapter sequences.

Qubit will be fine for amplicon libraries quantification where the PCR input was low so there is not much carry over of non-adapted DNA.
