Detecting Tripartite Steering via Quantum Entanglement
Entropy, 2022 Einstein-Podolsky-Rosen steering is a kind of powerful nonlocal quantum resource in quantum information processing such as quantum cryptography and quantum communication. Many criteria have been proposed in the past few years to detect steerability, both

Quantum steering on IBM quantum processors [PDF]
Physical Review A, 2022 We use contemporary quantum computers to experimentally investigate quantum steering of an open quantum system by measurements on its environment. On three IBM quantum processors we distinguish a qubit as the open system and perform pairwise interactions

Quantum steering with imprecise measurements [PDF]
Physical Review Letters, 2023 We study quantum steering experiments without assuming that the trusted party can perfectly control their measurement device. Instead, we introduce a scenario in which these measurements are subject to small imprecision.

Activation of post-quantum steering [PDF]
New Journal of PhysicsThere are possible physical theories that give greater violations of Bell’s inequalities than the corresponding Tsirelson bound, termed post-quantum non-locality.

Quick Quantum Steering: Overcoming Loss and Noise with Qudits [PDF]
Physical Review X, 2022 A primary requirement for a robust and unconditionally secure quantum network is the establishment of quantum nonlocal correlations over a realistic channel.

Is quantum steering spooky? [PDF]
, 2013 In quantum mechanics, if one party performs a measurement on one system, different outcomes can lead to different states for another system. This phenomenon is known as quantum steering.

Quantum steering ellipsoids [PDF]
, 2017 Graphical representations are invaluable for visualising physical systems and processes. In quantum information theory, the Bloch vector representation of a single qubit is ubiquitous, but visualising higher-dimensional quantum systems is far less ...

Quantum steering transfer within quantum network
New Journal of PhysicsQuantum steering is the ability that one system affects another one without delay by performing local measurements, which has garnered significant attention in the field of quantum information science. Here, we propose a linear network to realize tunable
