Displaced photon helicity states: a quantum realization of Arago-Fresnel interference
Yan Zhang, Xiang Liu, Hou Ian
The laws of Arago and Fresnel relate the polarization of light to its capacity for interference. We investigate their quantum counterpart at the level of the fundamental helicity s…

Phase-locked amplification enhanced by spin squeezing
Yan Zhang, Jing Zhang, Hou Ian
Quantum lock-in amplification raises the detection sensitivity of magnetic fields to unprecedented levels by phase-locked pumping the Zeeman levels of a single trapped atom. Howeve…
