One pure steered state implies Einstein-Podolsky-Rosen steering
Qiu-Cheng Song, Joonwoo Bae
In this work, we show that a two-qubit entangled state admitting at least one pure steered state is Einstein-Podolsky-Rosen (EPR) steerable from Alice to Bob. Pure steered states s…

Shareability of steering in 2-producible states
Qiu-Cheng Song, Travis J. Baker, Howard M. Wiseman
Quantum steering is the phenomenon whereby one party (Alice) proves entanglement by "steering'' the system of another party (Bob) into distinct ensembles of states, by performing d…

On the power of one pure steered state for EPR-steering with a pair of qubits
Qiu-Cheng Song, Travis J. Baker, Howard M. Wiseman
As originally introduced, the EPR phenomenon was the ability of one party (Alice) to steer, by her choice between two measurement settings, the quantum system of another party (Bob…
