Amplified Entanglement Assisted Communication Outperforming Classical Laser Communication in Strong Atmospheric Turbulence Regime
Contrary to the common belief that quantum entanglement is destroyed by amplification, in entanglement-assisted communication systems dominated by attenuation effects rather than noise, the signal photons can be amplified by the erbium-doped fiber amplifier (EDFA) without destroying the entanglement. The inventors developed a terrestrial free-space...

Method for On-Chip Squeezed and Entangled Light Generation
Quantum entanglement is as follows: entangled photons for transferring information between two nodes, in which the receiver holds half of the entangled photons while the sender holds the other half. Thus, communication and sensing are made possible by manipulation of these photons and/or observation of the changes of these photons. This invention...
