Surpassing the no-cloning limit with a heralded hybrid linear amplifier for coherent states
Nature Communications, 2016 Cloning an unknown quantum state is challenging and the limit on the quality of clones is set by the no-cloning theorem. Here, the authors demonstrated the surpassing of such a limit using an effective quantum cloner based on a hybrid probabilistic ...

Fundamental rate-loss tradeoff for the quantum internet [PDF]
, 2016 The quantum internet holds promise for performing quantum communication, such as quantum teleportation and quantum key distribution (QKD), freely between any parties all over the globe. Such a future quantum network, depending on the communication distance of the requesting parties, necessitates to invoke several classes of optical quantum ...

Creation and Detection of Vector Vortex Modes for Classical and Quantum Communication [PDF]
Journal of Lightwave Technology, 2017 Vector vortex beams are structured states of light that are nonseparable in their polarisation and spatial mode, they are eigenmodes of free-space and many fiber systems, and have the capacity to be used as information carriers for both classical and ...

Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...
