We show that a special type of measurements, called symmetric informationallycomplete positive operator-valued measures (SIC POVMs), provide a strongerentanglement detection criterion than the computable cross-norm or realignmentcriterion based on local orthogonal observables. As an illustration, wedemonstrate the enhanced entanglement detection power in simple systems ofqubit and qutrit pairs. This observation highlights the significance of SICPOVMs for entanglement detection.
