Fermionic steering and its monogamy relations in Schwarzschild spacetime
European Physical Journal C: Particles and Fields, 2022 Using two different types of quantification for quantum steering, we study the influence of Hawking radiation on quantum steering for fermionic fields in Schwarzschild spacetime.

A channel-based framework for steering, non-locality and beyond
New Journal of Physics, 2018 Non-locality and steering are both non-classical phenomena witnessed in nature as a result of quantum entanglement. It is now well-established that one can study non-locality independently of the formalism of quantum mechanics, in the so-called device ...

Reliable experimental certification of one-way Einstein-Podolsky-Rosen steering
Physical Review Research, 2022 Quantum steering is a recently defined form of quantum correlation which lies at the heart of quantum mechanics. In contrast to other types of quantum correlations, quantum steering is inherently asymmetric, which implies that it could manifest in one ...

A formalism for steering with local quantum measurements
New Journal of Physics, 2018 We develop a unified approach to classical, quantum and post-quantum steering. The framework is based on uncharacterised (black-box) parties performing quantum measurements on their share of a (possibly unphysical) quantum state, and its starting point ...

In situ upgrade of quantum simulators to universal computers [PDF]
, 2018 Quantum simulators, machines that can replicate the dynamics of quantum systems, are being built as useful devices and are seen as a stepping stone to universal quantum computers.

On Quantum Steering and Wigner Negativity
Quantum, 2023 Quantum correlations and Wigner negativity are two important signatures of nonclassicality in continuous-variable quantum systems. In this work, we investigate how both are intertwined in the context of the conditional generation of Wigner negativity.

Post-quantum steering is a stronger-than-quantum resource for information processing
npj Quantum Information, 2022 We present the first instance where post-quantum steering is a stronger-than-quantum resource for information processing – remote state preparation.

Quantum steering in tripartite quantum systems [PDF]
SCIENTIA SINICA Physica, Mechanica & Astronomica, 2018 Quantum steering is a kind of quantum feature between quantum entanglement and Bell non-locality. Due to its special asymmetry, quantum steering plays an important role in many aspects of quantum information processing and thus has been widely concerned.

Steering Witness and Steering Criterion of Gaussian States
Entropy, 2021 Quantum steering is an important quantum resource, which is intermediate between entanglement and Bell nonlocality. In this paper, we study steering witnesses for Gaussian states in continuous-variable systems.
