Certified coherent, informative, and non-entanglement-breaking fixed points of future-referential quantum feedback
Eran Kopel
We study quantum processes in which information extracted from a forward simulation is returned as input to an earlier internal time of the simulated dynamics: externally the proto…
First measurement of polarized spin-density matrix elements and differential cross sections d/d in ~photoproduction off the proton for GeV using CLAS at Jefferson Lab
T. Hu, Z. Akbar, V. Crede +147
We report on the differential cross sections d/d, the unpolarized spin-density matrix elements , , Re\,, and the first extraction of the polari…
Wavenumber-Domain Virtual Arrays for Holographic Near-Field Localization
Giovanni Iacovelli, Chandan Kumar Sheemar, Symeon Chatzinotas
Monostatic localization of multiple point targets is studied for a holographic aperture operated through wavenumber-domain modes. A specular-point condition delimits the validity o…
Stacked Intelligent Metasurfaces Assisted UAV Communications
Chandan Kumar Sheemar, Giovanni Iacovelli, Sourabh Solanki +2
In this paper, we investigate an unmanned aerial vehicle (UAV) communication system assisted by stacked intelligent metasurfaces (SIMs), which enable programmable wave-domain signa…
STAR Beyond Diagonal RISs with Amplification: Modeling and Optimization
Chandan Kumar Sheemar, Giovanni Iacovelli, Wali Ullah Khan +3
This paper develops a physically consistent signal model with hardware constraints for a simultaneous transmitting and reflecting beyond-diagonal RIS (STAR BD-RIS) endowed with per…
Visible Light Indoor Positioning with a Single LED and Distributed Single-Element OIRS: An Iterative Approach with Adaptive Beam Steering
Daniele Pugliese, Giovanni Iacovelli, Alessio Fascista +4
The integration of Optical Intelligent Reflective Surfaces (OIRSs) into Visible Light Communication (VLC) systems is gaining momentum as a valid alternative to RF technologies, har…
