Dynamic Continuous Variable Quantum Key Distribution for Securing a Future Global Quantum Network

Advanced Quantum Technologies, EarlyView.
The article explores securing a dynamic global quantum network using continuous variable QKD, proposing a unified three‐layer network architecture for integrating existing QKD networks. It evaluates secret key rates across various channels and introduces the link capacity as a metric for determining the optimum path for secret key distribution in a ...

Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

Direct Data‐Driven State‐Feedback Control of Linear Parameter‐Varying Systems

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT The framework of linear parameter‐varying (LPV) systems has shown to be a powerful tool for the design of controllers for complex nonlinear systems using linear tools. In this work, we derive novel methods that allow us to synthesize LPV state‐feedback controllers directly from only a single sequence of data and guarantee stability and ...
