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

open access: yesPhotonics, 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 ...

Generation of Three-Mode Entanglement Based on Parametric Amplifiers Using Quantum Entanglement Swapping

open access: yesPhotonics, 2022
Quantum entanglement swapping is one of the most promising quantum techniques to create or manipulate large-scale multi-mode entanglement between two distant quantum entangled systems.

Exponential Clustering of Bipartite Quantum Entanglement at Arbitrary Temperatures

open access: yesPhysical 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.

Blindly verifying partially unknown entanglement

open access: yesiScience, 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,

Entanglement generation and self-correcting quantum memories [PDF]

open access: yes, 2012
Building a working quantum computer that is able to perform useful calculations remains a challenge. With this thesis, we are trying to contribute a small piece to this puzzle by addressing three of the many fundamental questions one encounters along the

Coherent Control of Entanglement with Atomic Ensembles [PDF]

open access: yes, 2011
Quantum networks are composed of quantum nodes which coherently interact by way of quantum channels. They offer powerful capabilities for quantum computation, communication, and metrology. A generic requirement for these realizations is the capability to
