Abstract

We present separability criteria based on local symmetric measurements. These experimental plausible criteria are shown to be more efficient in detecting entanglement than the current counterparts by detailed examples. Furthermore, we generalize the separability criteria from bipartite to arbitrary multipartite systems. These criteria establish a richer connection between the quantum entanglement and the probabilities of local measurement outcomes.

Why This Paper Matters

  • It adds a 2025 reference point for readers tracking recent quantum research.
  • We present separability criteria based on local symmetric measurements.
