Abstract: In this talk, I will first give a brief introduction to quantum entanglement
and its detection. Then I will explain the basic concept of randomized measurements
and show their usefulness in characterizing entanglement in an experimentally friendly
manner [1]. Moreover, I will review our results which are systematic methods to detect
even weak forms of entanglement [2], spin-squeezing entanglement [3]. Finally, I will
discuss the relation between multipartite entanglement and the structure constants of
Lie algebra [4].

Comment: In this seminar, I do not assume any background in quantum entanglement
and quantum information. I am very welcome theoreticians and experimentalists from
different backgrounds.
