**Abstract:**

Symmetric multi-qubit quantum states are important in quantum information. A lot of well-known states, such as W, GHZ or Dicke states are symmetric. They appear in a large number of quantum protocols and algorithms. They are also good candidates to propose highly entangled states. In this talk I'll present how the question of their classification and the research of highly entangled states is tackled in the quantum information literature and what classical algebraic geometry has to say about it. I'll also propose some experimental work to connect the two pictures.
