In this talk, we discuss various uncertainty principles on quantum symmetries in quantum Fourier analysis. We show that uncertainty principles are robust when classical group symmetries are replaced by quantum symmetries, captured by von Neumann algebras. In recent work joint with Linzhe Huang and Jinsong Wu, we study a quantum analogue of the Widgerson-Widgerson uncertainty principle and give a complete answer to their conjecture.    </p>
