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,

Experimental realization of multipartite entanglement via quantum Fisher information in a uniform antiferromagnetic quantum spin chain

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 ...

Estimation of the Influence of a Noisy Environment on the Binary Decision Strategy in a Quantum Illumination Radar

Sensors, 2022
A quantum illumination radar uses quantum entanglement to enhance photodetection sensitivity. The entanglement is quickly destroyed by the decoherence in an environment, although the sensitivity enhancement could survive thanks to quantum correlations ...

Measuring statistics-induced entanglement entropy with a Hong–Ou–Mandel interferometer

Nature Communications
Despite its ubiquity in quantum computation and quantum information, a universally applicable definition of quantum entanglement remains elusive. The challenge is further accentuated when entanglement is associated with other key themes, e.g., quantum ...

Macroscopic and deterministic quantum feature generation via phase basis quantization in a cascaded interferometric system

Scientific Reports, 2021
Quantum entanglement is the quintessence of quantum information science governed by quantum superposition mostly limited to a microscopic regime. For practical applications, however, macroscopic entanglement has an essential benefit for quantum sensing ...

Quantifying entanglement for unknown quantum states via artificial neural networks

Scientific Reports
Quantum entanglement acts as a crucial part in quantum computation and quantum information, hence quantifying unknown entanglement is an important task. Due to the fact that the amount of entanglement cannot be achieved directly by measuring any physical
