On the power of one pure steered state for EPR-steering with a pair of qubits [PDF]

New Journal of Physics, 2023
As originally introduced, the Einstein, Podolsky and Rosen (EPR) phenomenon was the ability of one party (Alice) to steer, by her choice between two measurement settings, the quantum system of another party (Bob) into two distinct ensembles of pure ...

Distillation of Multipartite Gaussian EPR Steering Based on Measurement-Based Noiseless Linear Amplification

Photonics
Multipartite Gaussian Einstein–Podolsky–Rosen (EPR) steering is a key resource for quantum networks, but in practice it is strongly degraded by channel loss and excess noise.

Manipulation and enhancement of Einstein-Podolsky-Rosen steering between two mechanical modes generated by two Bogoliubov dissipation pathways

Physical Review Research, 2023
We consider a three-mode optomechanical system in which two mechanical oscillators are independently coupled to a cavity mode driven by two controllable lasers.

Remote asymmetric Einstein-Podolsky-Rosen steering of magnons via a single pathway of Bogoliubov dissipation

Physical Review Research, 2022
We propose a scheme to generate remote asymmetric Einstein-Podolsky-Rosen (EPR) steering of two magnon modes in a hybrid ferromagnet-superconductor system.

Quantum Steering: Practical Challenges and Future Directions

PRX Quantum, 2022
Einstein-Rosen-Podolsky (EPR) steering or quantum steering describes the “spooky action at a distance” that one party is able to remotely alter the states of the other if they share a certain entangled state.

Certification and applications of quantum nonlocal correlations

JPhys Photonics, 2023
Entanglement and Einstein–Podolsky–Rosen (EPR) steering are nonlocal quantum correlations, which are relevant resources for quantum information protocols. EPR steering, or quantum steering, refers to the correlation where a party might ‘steer’, or modify,

Objective methods for the assessment of passenger car steering quality [PDF]

, 2002
Steering feel and quality are terms commonly used in the automotive industry when describing passenger car steering systems. However, a procedure for the quantification of these terms does not exist, let alone a concise definition of what they ...

Einstein-Podolsky-Rosen entanglement and asymmetric steering between distant macroscopic mechanical and magnonic systems

Physical Review Research, 2021
We propose a deterministic scheme for establishing hybrid Einstein-Podolsky-Rosen (EPR) entanglement channel between a macroscopic mechanical oscillator and a magnon mode in a distant yttrium-iron-garnet (YIG) sphere across about 10 GHz of frequency ...

Measurement-Based Control of Quantum Entanglement and Steering in a Distant Magnomechanical System

Photonics, 2023
In this paper, we propose a scheme for measurement-based control of hybrid Einstein–Podolsky–Rosen (EPR) entanglement and steering between distant macroscopic mechanical oscillator and yttrium iron garnet (YIG) sphere in a system of an electromechanical ...

Einstein-Podolsky-Rosen Steering Inequalities and Applications

Entropy, 2018
Einstein-Podolsky-Rosen (EPR) steering is very important quantum correlation of a composite quantum system. It is an intermediate type of nonlocal correlation between entanglement and Bell nonlocality.
