Multipartite Entanglement in Stabilizer Tensor Networks

Understand

Despite the fundamental importance of quantum entanglement in many-body systems, our understanding is mostly limited to bipartite situations.

• Indeed, even defining appropriate notions of multipartite entanglement is a significant challenge for general quantum systems.
• In this work, we initiate the study of multipartite entanglement in a rich, yet tractable class of quantum states called stabilizer tensor networks.
• We demonstrate that, for generic stabilizer tensor networks, the geometry of the tensor network informs the multipartite entanglement structure of the state.
