Macroscopic Spin GHZ States with a Levitated Ferromagnet
Xueqi Ni, Zhixing Zou, Ping Koy Lam +2
The generation of macroscopic quantum states can drive both fundamental physics and quantum technologies. This work proposes a top-down approach to the generation of macroscopic sp…

Microscopic theory of a precessing ferromagnet for ultrasensitive magnetometry
Xueqi Ni, Zhixing Zou, Ruvi Lecamwasam +5
Levitated systems have great potential in quantum sensing and exploring quantum effects at the macroscopic scale. Of particular interest are recent works suggesting that a levitate…

A Van der Waals Moiré Bilayer Photonic Crystal Cavity
Lesley Spencer, Nathan Coste, Xueqi Ni +9
Enhancing light-matter interactions with photonic structures is critical in classical and quantum nanophotonics. Recently, Moiré twisted bilayer optical materials have been propos…
