- Abstract: Detection of entanglement through partial knowledge of the quantum state is a
challenge to implement efficiently. Here we propose a separability criterion
for detecting bipartite entanglement in arbitrary dimensional quantum states
using partial moments of the realigned density matrix. Our approach enables
detection of both distillable and bound entangled states through a common
framework. We illustrate the efficiency of our method through examples of
states belonging to both the above categories, which are not detectable using
comparable other schemes relying on partial state information. The formalism of
employing partial realigned moments proposed here is further shown to be
effective for two-qubit systems too, with a slight modification of our
separability criterion.
