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…
Continuous Quantum Aperture: Beamforming with a Single-Vapor-Cell Rydberg Receiver
Mingyao Cui, Qunsong Zeng, Minze Chen +6
Beamforming is conventionally understood as a collective property of many discrete antenna elements in both communication and radar fields, which links angular selectivity to array…
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…
