Topologically protected quantum entanglement emitters

Nature Photonics, 2021
Entanglement and topology portray nature at the fundamental level but differently. Entangled states of particles are intrinsically sensitive to the environment, whereas the topological phases of matter are naturally robust against environmental ...

The Effect of Quantum Noise on Multipartite Entanglement from a Cascaded Parametric Amplifier

Photonics, 2023
The tripartite entanglement generated from a cascaded parametric amplifier is always present in the whole gain region in the ideal condition. However, in practical applications, the quantum entanglement is very fragile and easily deteriorated by quantum ...

Quantum Entanglement of Monochromatic and Non-Monochromatic Photons on a Waveguide Beam Splitter

Entropy, 2021
It is well known that the waveguide beam splitter can be used as a source for the quantum entanglement of photons. The analysis of such quantum entanglement is a difficult problem even for monochromatic photons, since the system under study is ...

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,

Exponential Clustering of Bipartite Quantum Entanglement at Arbitrary Temperatures

Physical Review X, 2022
Many inexplicable phenomena in low-temperature many-body physics are a result of macroscopic quantum effects. Such macroscopic quantumness is often evaluated via long-range entanglement, that is, entanglement in the macroscopic length scale.

Entanglement-enhanced quantum metrology: From standard quantum limit to Heisenberg limit [PDF]

Applied Physics Reviews
Entanglement-enhanced quantum metrology explores the utilization of quantum entanglement to enhance measurement precision. When particles in a probe are prepared into a suitable quantum entangled state, they may collectively accumulate information about ...
