Two-axis spin squeezing of two-component BEC via a continuous driving
Wen Huang, Yan-Lei Zhang, Chang-Ling Zou +2
In two-component BEC, the one-axis twisting Hamiltonian leads to spin squeezing with the limitation that scales with the number of atoms as . We propose a scheme…
Incoherent control of electromagnetically induced transparency and Aulter-Townes splitting
Chang-Ling Zou, Yan-Lei Zhang, Liang Jiang +2
The absorption and dispersion of probe light is studied in an unified framework of three-level system, with coherent laser driving and incoherent pumping and relaxation. The electr…
Brillouin scattering induced transparency and non-reciprocal light storage
Chun-Hua Dong, Zhen Shen, Chang-Ling Zou +3
Stimulated Brillouin scattering (SBS) is a very fundamental interaction between light and travelling acoustic waves, which is mainly attributed to the electrostriction and photoela…
Transmission of Photonic Quantum Polarization Entanglement in a Nanoscale Hybrid Plasmonic Waveguide
Ming Li, Chang-Ling Zou, Xi-Feng Ren +5
Photonic quantum technologies have been extensively studied in quantum information science, owing to the high-speed transmission and outstanding low-noise properties of photons. Ho…
Detuning Enhanced Cavity Spin Squeezing
Yan-Lei Zhang, Chang-Ling Zou, Xu-Bo Zou +2
The unconditionally squeezing of the collective spin of an atomic ensemble in a laser driven optical cavity (I. D. Leroux, M. H. Schleier-Smith, and V. Vuletic, Phys. Rev. Lett 104…
Strongly coupled magnons and cavity microwave photons
Xufeng Zhang, Chang-Ling Zou, Liang Jiang +1
We realize a cavity magnon-microwave photon system in which magnetic dipole interaction mediates strong coupling between collective motion of large number of spins in a ferrimagnet…
High visibility on-chip quantum interference of single surface plasmons
Yong-Jing Cai, Ming Li, Xi-Feng Ren +6
Quantum photonic integrated circuits (QPICs) based on dielectric waveguides have been widely used in linear optical quantum computation. Recently, surface plasmons have been introd…
