Experimental certification of steering criterion based on general entropic uncertainty relation

Understand

Quantum steering describes the phenomenon that one system can be immediately influenced by another with local measurements.

• It can be detected by the violation of a powerful and useful steering criterion from general entropic uncertainty relation.
• This criterion, in principle, can be evaluated straightforwardly and achieved by only probability distributions from a finite set of measurement settings.
• Herein, we experimentally verify the steering criterion by means of the two-photon Werner-like states and three Pauli measurements.
