Experimental study on all-fiber-based unidimensional continuous-variable quantum key distribution

Xuyang Wang, Wenyuan Liu, Pu Wang, and Yongmin Li.

  We experimentally demonstrated an all-fiber-based unidimensional continuous-variable quantum key distribution (CV QKD) protocol and analyzed its security under collective attack in realistic conditions...

Suppression of phonon tunneling losses by microfiber strings for high-Q membrane microresonators

Zongyang Li, Qiang Zhang, Xiang You, Yongmin Li, et al.

  We propose to utilize a microfiber string to isolate the tunneling of acoustic waves between amembrane frame and its holder. The displacement response of the membrane...

Quantum analysis and experimental investigation of the nondegenerate optical parametric oscillator with unequally injected signal and idler

Ning Wang, and Yongmin Li.

  We developed a quantum analysis of the nondegenerate optical parametric oscillator (NOPO) with unequally injected signal and idler. Both the steady-state output field...

Physical Review A, 93, 013831 (2016).


Quantum frequency up-conversion of continuous variable entangled states

Wenyuan Liu, Ning Wang, Zongyang Li, and Yongmin Li.

  We demonstrate experimentally quantum frequency up-conversion of a continuous variable entangled optical field via sum-frequency-generation process...
