Physical Review Research, 2020 Quantum entanglement is a quantum-mechanical phenomenon where the quantum state of a many-body system with many degrees of freedom cannot be described independently of the state of each body with a given degree of freedom, no matter how far apart in ...

Entanglement Access Control for the Quantum Internet [PDF]
, 2019 Quantum entanglement is a crucial element of establishing the entangled network structure of the quantum Internet. Here we define a method to achieve controlled entanglement access in the quantum Internet. The proposed model defines different levels of entanglement accessibility for the users of the quantum network.

Physical Resources for Quantum-enhanced Phase Estimation
, 2016 We study the role of quantum entanglement (particle entanglement and mode entanglement) in optical phase estimation by employing the first and second quantization formalisms of quantum mechanics.

Correcting Quantum Errors with Entanglement [PDF]
, 2006 We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction. The entanglement-assisted quantum codes we describe do not require the dual-containing constraint necessary for standard quantum error ...

Blindly verifying partially unknown entanglement
iScience, 2022 Summary: Quantum entanglement has shown distinguished features beyond any classical state. Many methods have been presented to verify unknown entanglement with the complete information about the density matrices by quantum state tomography. In this work,

Cloning quantum entanglement in arbitrary dimensions [PDF]
Phys. Rev. A 72, 042314 (2005), 2005 We have found a quantum cloning machine that optimally duplicates the entanglement of a pair of $d$-dimensional quantum systems. It maximizes the entanglement of formation contained in the two copies of any maximally-entangled input state, while preserving the separability of unentangled input states.

Entanglement dynamics in chaotic systems [PDF]
, 2004 We study quantum chaos for systems with more than one degree of freedom, for which we present an analysis of the dynamics of entanglement. Our analysis explains the main features of entanglement dynamics and identifies entanglement-based signatures of ...

Quantum Entanglement in Deep Learning Architectures. [PDF]
Physical Review Letters, 2018 Modern deep learning has enabled unprecedented achievements in various domains. Nonetheless, employment of machine learning for wave function representations is focused on more traditional architectures such as restricted Boltzmann machines (RBMs) and ...
