Conditioning-Free Non-Uniform Quantum Fourier and Chebyshev Transforms
Chaowen Guan, Akshit Katiyar
We present an efficient quantum algorithm for the non-uniform Chebyshev transform. It is defined as the projection of a function onto Chebyshev polynomials sampled at given nodes t…

Quantum Kravchuk Transform using fast-forwarding
Chaowen Guan, Akshit Katiyar
We present a quantum algorithm for the Kravchuk transform that scales logarithmically in both the dimension and the inverse of the error parameter. The quantum Kravchuk transform m…
