We analyze and experimentally demonstrate quantum steering using criteria based on
generalized entropies and criteria with minimal assumptions based on the so-called …

The set of all qubit states that can be steered to by measurements on a correlated qubit is
predicted to form an ellipsoid—called the quantum steering ellipsoid—in the Bloch ball. This …

Within the framework of quantum refereed steering games, quantum steerability can be
certified without any assumption on the underlying state nor the measurements involved …

The quantum steering ellipsoid visualizes the set of all qubit states that can be steered by
measuring on another correlated qubit in the Bloch picture. Together with local reduced …

We use contemporary quantum computers to experimentally investigate quantum steering of
an open quantum system by measurements on its environment. On three IBM quantum …

The effect of quantum steering describes a possible action at a distance via local
measurements. In the last few years, several criteria have been proposed to detect this type …

Abstract Einstein–Podolsky–Rosen (EPR) steering is an intermediate form of nonlocality
which interpolates between entanglement and Bell nonlocality. It has been shown that EPR …

Violating a nonlocality inequality enables the most powerful remote quantum information
tasks and fundamental tests of quantum physics. Loophole-free photonic verification of …

Quantum entanglement is a key resource for foundational quantum information and
communication tasks, such as teleportation, entanglement swapping and quantum key …
