Within the hierarchy of inseparable quantum correlations, Einstein-Podolsky-Rosen steering is distinguished from both entanglement and Bell nonlocality by its asymmetry-there exist conditions where the steering phenomenon changes from being observable to not observable, simply by exchanging the role of the two measuring parties. While this one-way steering feature has been previously demonstrated for the restricted class of Gaussian measurements, for the general case of positive-operator-valued…

Experimental Quantification of Asymmetric Einstein-Podolsky-Rosen Steering.
TLDR
This work experimentally demonstrate asymmetric EPR steering for a class of two-qubit states in the case of two measurement settings and provides new insight into the fundamental asymmetry of quantum nonlocality and has potential applications in asymmetric quantum information processing.
Conclusive Experimental Demonstration of One-Way Einstein-Podolsky-Rosen Steering.
TLDR
This work presents the first experimental demonstration of one-way steering free of significant limiting assumptions, using a new sufficient condition for nonsteerability and using a novel source of extremely high-quality photonic Werner states.
Reliable experimental certification of one-way Einstein-Podolsky-Rosen steering
TLDR
An experiment demonstrating one-way steering for the two-qubit entangled system based on a newly-developed orbital angular momentum platform is reported, which resolves the subtlety in the dimensionality and further the ambiguity in existing data of previous demonstrations, and provides a universal method to characterize one- way steering effect for two- qubit states.

Einstein–Podolsky–Rosen steering testing via quantum measurement
Einstein–Podolsky–Rosen (EPR) steering is a method that is used to analyze the physical inseparability of a quantum system state. Theoretically, the preferences of EPR steering behaviour in the
Manipulating the direction of Einstein-Podolsky-Rosen steering
Einstein-Podolsky-Rosen (EPR) steering exhibits an inherent asymmetric feature that differs from both entanglement and Bell nonlocality, which leads to one-way EPR steering. Although this oneway EPR
Einstein-Podolsky-Rosen Steering for Mixed Entangled Coherent States
TLDR
Without the memory stored in the environment, some of the initial states with maximal values of quantum steering, Bell nonlocality, and entanglement can provide a delayed loss of that value during temporal evolution, which is of interest to the current study.
One-way Einstein-Podolsky-Rosen steering beyond qubits
Quantum steering has been exploited as an important resource in modern quantum information processing. Owing to its directional nature, some quantum states that are asymmetric under the exchange of

Inequivalence of entanglement, steering, and Bell nonlocality for general measurements
Einstein-Podolsky-Rosen steering is a form of inseparability in quantum theory commonly acknowledged to be intermediate between entanglement and Bell nonlocality. However, this statement has so far

Einstein-Podolsky-Rosen steering is a form of quantum nonlocality exhibiting an inherent asymmetry between the observers, Alice and Bob. A natural question is then whether there exist entangled
Quantifying Einstein-Podolsky-Rosen steering.
TLDR
It is shown that every pure entangled state is maximally steerable and the projector onto the antisymmetric subspace is maximALLY steerable for all dimensions; a new example of one-way steering is provided and strong support is given that states with positive-partial transposition are not steerable.

Steering, entanglement, nonlocality, and the Einstein-Podolsky-Rosen paradox.
TLDR
An operational definition is provided, from which it is proved that steerable states are a strict subset of the entangled states, and a strict superset of the states that can exhibit Bell nonlocality.
Necessary and sufficient quantum information characterization of Einstein-Podolsky-Rosen steering.
TLDR
It is proved that, for any bipartite steerable state, there are instances of the quantum subchannel discrimination problem for which this state allows a correct discrimination with strictly higher probability than in the absence of entanglement, even when measurements are restricted to local measurements aided by one-way communication.

Recent theory predicts that Einstein–Podolsky–Rosen arguments enable an effect in which one party can steer the other but not the converse. Researchers have now demonstrated this one-way steering
