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 explain our results which are systematic methods to detect even weak forms of entanglement [2] and spin-squeezing entanglement [3]. Finally, I will discuss further applications to teleportation or Bell inequalities [4] and statistical significant tests [5].

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.
