Quantum correlated photons via a passive nonlinear microcavity
Mengdi Zhao, Yunkai Wang, Shanhui Fan +1
Photons, by nature, typically do not exhibit interactions with each other. Creating photon-photon interactions holds immense importance in both fundamental physics and quantum tech…
Few-photon transport via a multimode nonlinear cavity: theory and applications
Yunkai Wang, Kejie Fang
Few-photon transport via waveguide-coupled local quantum systems has attracted extensive theoretical and experimental studies. Most of the study has focused on atomic or atomic-lik…
Continuous-variable graph states for quantum metrology
Yunkai Wang, Kejie Fang
Graph states are a unique resource for quantum information processing, such as measurement-based quantum computation. Here, we theoretically investigate using continuous-variable g…
Absolute magnetometry based on quantum beats in diamond nitrogen-vacancy centers
Kejie Fang, Victor M. Acosta, Charles Santori +5
We demonstrate an absolute magnetometer immune to temperature fluctuation and strain inhomogeneity, based on quantum beats in the ground state of nitrogen-vacancy centers in diamon…
