Entanglement Hamiltonian and effective temperature of non-Hermitian quantum spin ladders

SciPost Physics Core
Quantum entanglement plays a crucial role not only in understanding Hermitian many-body systems but also in offering valuable insights into non-Hermitian quantum systems.

Does acceleration always degrade quantum entanglement for tetrapartite Unruh-DeWitt detectors?

Journal of High Energy Physics
Previous studies have shown that the Unruh effect completely destroys quantum entanglement and coherence of bipartite states, as modeled by entangled Unruh-DeWitt detectors.

Restriction on the local realism violation in three-qubit states and its relation with tripartite entanglement

Scientific Reports, 2018
Quantum entanglement and non-locality are two special aspects of quantum correlations. The relationship between multipartite entanglement and non-locality is at the root of the foundations of quantum mechanics but there is still no general quantitative ...

Entanglement measure for any quantum states [PDF]

arXiv, 2003
The entanglement measure for multiqudits is proposed. This measure calculates the partial entanglement distributed by subsystems and the complete entanglement of the total system. This shows that we need to measure the subsystem entanglements to explain the full description for multiqudit entanglement. Furthermore, we extend the entanglement measure to

Metaheuristic optimization scheme for quantum kernel classifiers using entanglement-directed graphs

ETRI Journal
Entanglement is crucial for achieving quantum advantages. However, in the context of quantum machine learning, existing optimization strategies for generating quantum classifier circuits often result in unentangled circuits, indicating an ...
