Broadband and Enhanced Second‐Harmonic Generation in Metallic 3R‐TaS2

Small, EarlyView.
A pronounced and robust SHG response has been observed in metallic 3R‐TaS2. It shows broadband SH conversion from 1020 nm to 1410 nm. Moreover, compared to the sapphire substrate, 3R‐TaS2 flakes with various thicknesses on the gold substrate showed different SHG enhancement; the enhancement factors range from 2.7 to 45.5.

Metrology for Quantum Hardware Standardization—Charting a Pathway: A Strategic Review

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 9, Page 1282-1296, September 2026.
Advances in quantum mechanics have long underpinned metrology by enabling practical realizations of units through quantum effects. With the 2019 SI revision, traceability is anchored in defined fundamental constants, reinforcing the quantum‐mechanical basis of modern standards. In parallel, quantum technologies are transitioning from laboratory science
