Quantum Fourier transform toolbox
Carli Bruinsma, Pietro M. Posta, Joppe Stokvis +2
Quantum Fourier transforms (QFTs) are essential primitives in quantum algorithms. While abelian groups admit efficient QFT circuits, with circuit size polynomial in the logarithm o…

Hidden shift problem for complex functions
Serge Adonsou, Peter Bruin, Maris Ozols +1
We study quantum algorithms for the hidden shift problem of complex scalar- and vector-valued functions on finite abelian groups. Given oracle access to a shifted function and the…
