Author(s): Lin Htoo Zaw, Jiajie Guo, Qiongyi He, Matteo Fadel, and Shuheng Liu Wigner negativity and genuine multipartite entanglement (GME) are key nonclassical resources that enable computational advantages and broader quantum-information tasks. In this Letter, we prove two theorems for multimode continuous-variable systems that relate these nonclassical resources. Both theo… [Phys. Rev. Lett. 137, 040202] Published Thu Jul 23, 2026
