Uncovering Non-Gaussianity through Multi-Copy Symmetries
Hao Dai, Yue Zhang
Gaussian states are fundamental in continuous-variable quantum information, yet characterizing non-Gaussianity remains challenging due to the non-convexity of the Gaussian set. Exi…

Spin minimum uncertainty states for refined uncertainty relations
Hao Dai, Yue Zhang
Minimum uncertainty states of the conventional Heisenberg uncertainty relation have been extensively studied and are often regarded as the most classical quantum states from the pe…
