Beating the Bad-Cavity Limit via Auxiliary-Emitter Linewidth Squeezing
Youke Xu, Zeyang Liao, Xue-hua Wang
Strong coupling in cavity QED is conventionally achieved at the expense of either high cavity quality factors or ultrasmall mode volumes, a trade-off that fundamentally constrains…

Phase estimation via multi-photon subtraction inside the SU(1,1) interferometer
Q. Q. Kang, Z. K. Zhao, Y. K. Xu +3
To improve the phase sensitivity, multi-photon subtraction schemes within the SU(1,1) interferometer are proposed. The input states are the coherent state and the vacuum state, and…
