Postselected amplification and photon recycling applied to optical sensing of magnetic fields

Yazhi Niu, Jialin Li, Lupei Qin +1

We apply the combined technique of postselected amplification and photon-recycling to an optical setup of magnetic field precision measurement. We propose two recycling schemes and…

Optical phase estimation via homodyne measurement in the presence of saturation effect of photodetectors

Jialin Li, Yazhi Niu, Lupei Qin +1

For optical phase estimation via homodyne measurement, we generalize the theory from detector's linear to nonlinear response regime, which accounts for the presence of saturation e…
