Rapid and high-sensitive NV-based microwave field imaging via digital lock-in amplification for on-chip microstrip diagnostics
Zijin Fu, Yanjie Liu, Hongliang Wu +6
High-resolution, high-sensitivity microwave (MW) magnetic field imaging is indispensable for non-destructive integrated circuit (IC) testing, radio-frequency device characterizatio…
On-chip Radio Frequency Maser
Hongliang Wu, Zhengtao Wang, Yuchen Han +6
Room-temperature solid-state masers offer exceptional frequency selectivity and ultra-low noise for weak-signal detection. However, their reliance on bulky metallic resonators has…
Detecting Axion Dark Matter with an Organic Molecular Maser
Hongliang Wu, Yuchen Han, Zhengtao Wang +7
We present a novel quantum sensing approach to search for axion-electron interactions around the axion mass of 6 \mueV. In this region, laboratory searches are relatively scarce, a…
Ultra-sensitive solid-state organic molecular microwave quantum receiver
Bo Zhang, Yuchen Han, Hong-Liang Wu +9
High-accuracy microwave sensing is widely demanded in various fields, ranging from cosmology to microwave quantum technology. Quantum receivers based on inorganic solid-state spin…
