Statistical verifications and deep-learning predictions for satellite-to-ground quantum atmospheric channels

Communications Physics, 2022
This study confirms that a classical channel model can be used for describing random fluctuations in LEO-to-ground quantum atmospheric channels. It shows that practical engineering designs for future QKD missions can be conveniently conducted using the ...

Probing Near‐Field EM Fluctuations in Superparamagnetic CoFeB With NV Quantum Dephasometry

Advanced Optical Materials, EarlyView.
We non‐invasively investigate the superparamagnetic spin dynamics of a 1.1 nm CoFeB layer by probing its near‐field EM fluctuations using NV centers‐based quantum dephasometry. Our findings are further supported by theoretical modeling and SQUID‐based magnetization characterization. These results provide critical insight into the magnetization dynamics

Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption

Advanced Optical Materials, EarlyView.
ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.

Neodymium‐Doped Nanocrystals for Sensing Cellular Temperature at the Nanoscale

Advanced Optical Materials, EarlyView.
Neodymium‐doped NaYF4 nanocrystals are engineered as bright, biocompatible nanothermometers for intracellular temperature mapping. Their ratiometric near‐infrared emission enables highly sensitive, nanoscale thermal readouts in living cells. Combined with gold nanostars for photothermal therapy, they reveal pronounced subcellular heating heterogeneity ...

Unraveling and Mitigating Resolution Loss in UV‐Assisted Vapor Phase Polymerization of Monolithic PEDOT:Tosylate Electrochromic Patterns

Advanced Optical Materials, EarlyView.
This work aims to understand the origin of pattern deviation in PEDOT:Tos films formed via vapor phase polymerization on UV‐exposed oxidant. UV exposure induces formation of loosely bound water which diffuses and produces macroscopic structuring at increased block copolymer contents.
