Lensing and enhanced single atom detection via a single-pixel nanostructure
Ling-Xiao Wang, Lei Xu, Ai-Ping Liu +7
We propose and demonstrate a general mechanism for nanoscale lensing based on the phase gradient imposed by a single nanostructure scattering light in its near-field. We verify thi…

Unitary and efficient spin squeezing in cavity optomechanics
Lei Xie, Zhiqi Yan, Lingxia Wang +5
We propose an approach to produce spin squeezed states of a large number of nitrogen-vacancy centers in diamond nanostructures coupled to an optical cavity. Unlike the previous squ…

Entangling spins using cubic nonlinear dynamics
Lingxia Wang, Yani Wang, Yujing Cheng +9
Entangled states with a large number of atomic spins are a key ingredient for quantum information processing and quantum metrology. Nowadays, the preparation of such states has…
