The Quantum Fourier Transform can be a rather tricky concept to get your head around. Postdoctoral researcher Ben Criger at QuTech will, therefore, discuss a geometric picture for deriving the coefficients of this advanced quantum algorithm. Also, he will look at an example on two qubits.

Can you find the circuit decomposition that Ben mentions at the end of the video?
