Loop Quantum Photonic Chip for Coherent Multi‐Time‐Step Evolution

Laser &Photonics Reviews, EarlyView.
A loop quantum photonic chip (Loop‐QPC) enabling efficient multi‐step quantum simulation in a single run is demonstrated. Combining recirculating loops with cycle‐or‐measure control, Loop‐QPC eliminates repeated reprogramming and reduces loss. Experimental demonstration of three‐step unitary evolution confirms high‐fidelity operation, showcasing the ...

Influence of the amplifier sharing tecnique in pipeline analog-to digital converters (ADCs)

, 2009
Three 12 bit, 40 MS/s pipelined analog-to-digital-converters (ADCs) are developed in 0.35μm CMOS process with 3.3V single power supply. The proposed ADCs architectures study the influence of the amplifier sharing technique in the power consumption and the main performances in the pipeline ADCs.

Atmospheric Corrosion Protection of LPBF Manufactured AlSi10Mg by Combining SiOx‐CVD and PDMS Grafting

Materials and Corrosion, EarlyView.
Hybrid SiOₓ‐CVD/PDMS ultrathin films mitigate atmospheric corrosion of additively manufactured AlSi10Mg. Electrochemical analyses show reduced corrosion currents, increased charge‐transfer resistance, and suppressed pitting due to diminished cathodic activity and limited oxygen and ion transport under NaCl exposure.

Four Directions, One Solution: Enabling Rapid Diffusion Tensor MRI for Ultra‐Low Field Using Deep Learning

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study revisits the tetrahedral encoding strategy originally proposed to accelerate Diffusion Tensor Magnetic Resonance Imaging (DT‐MRI) by reducing the requisite number of diffusion‐weighted measurements to four. We examine its practical limitations and explore how artificial intelligence (AI) can extend its utility. Specifically,

Low‐Complexity Hybrid Beamforming for LEO Satellites: Beam Update Rate Analysis and Advanced Adaptive Precoding

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Low Earth Orbit (LEO) satellite constellations offer unprecedented opportunities for global broadband connectivity but pose significant beamforming challenges due to rapid platform motion and stringent onboard hardware constraints. Fully digital architectures, while optimal in theory, remain impractical for satellite payloads, motivating ...

CLEAR Interference Cancellation in a Wideband Dual‐Channel Receiver for Independent Satellite Multi‐Connectivity Links

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this paper, the correlation learning estimation and adaptive reduction (CLEAR) of interference, an adaptive, blind and transparent interference compensation method applied in a wideband dual‐channel receiver, is studied for a pair of independent satellite multi‐connectivity links, using the same carrier frequency and signal bandwidth in use
