Researchers have quantified the probability of observing quantum steering in generic two-qubit states. Steering is a manifestation of entanglement where measurements performed by one party influence the conditional states of another, without the correlations being explainable by a local hidden state model. This study addresses the question of how common this behavior is in quantum systems, which is crucial for the development of quantum information technologies.

The team derived analytical expressions for the steering probability ($\mathcal{P}_S$) in Werner states for two- and three-setting scenarios, restricting the latter case to coplanar projective measurements on the Bloch sphere. For a larger number of settings and various random state ensembles, numerical analyses showed that $\mathcal{P}_S$ systematically increases with the number of measurements. Furthermore, this probability substantially exceeds the probabilities associated with Bell nonlocality.

The results indicate that random states with minimal environmental coupling exhibit a high probability of steering for a finite number of measurements ($m$), approaching genuine typicality, where $\mathcal{P}_S = 100\%$, as the number of settings increases. The study provides a detailed characterization of $\mathcal{P}_S$ across different state ensembles and specific families, such as Werner and Bell-diagonal states, identifying those with the greatest non-classical potential and highlighting their relevance for protocols where steering serves as a key resource in quantum communication and computation.
