Duality constrains optimal thresholds in quantum error correction
Lucas H. English, Haoyuan Luo, Yangming Wang +3
Error correction thresholds are often treated as the primary figure of merit for comparing quantum error-correcting code families. We show that the optimal error correction thresho…

Non-Gaussian Photon Correlations in Weakly Coupled Atomic Ensembles
Yangming Wang, Sahand Mahmoodian
We develop a scattering theory formalism and use it to predict that a resonantly driven atomic ensemble weakly coupled to an optical mode can generate light with non-Gaussian corre…

Theory of Three-Photon Transport Through a Weakly Coupled Atomic Ensemble
Yangming Wang, Noe Demazure, Sahand Mahmoodian
Understanding multi-photon interactions in non-equilibrium quantum systems is an outstanding challenge in quantum optics. In this work, we develop an analytical and diagrammatic fr…
