One pure steered state implies Einstein-Podolsky-Rosen steering for two-qubit entangled states
The work proves that if one party can steer another two-qubit entangled state to at least one pure steered state, the state is two-way EPR steerable. This means Alice and Bob can both perform remote operations on their shared quantum system. The key finding is that the existence of such a pure steered state implies Einstein-Podolsky-Rosen (EPR) steering for any two-qubit entangled state, establishing a generalized Gisin theorem.
