Wavelets and Wavelet Packets on Quantum Computers [PDF]
, 1999 We show how periodized wavelet packet transforms and periodized wavelet transforms can be implemented on a quantum computer. Surprisingly, we find that the implementation of wavelet packet transforms is less costly than the implementation of wavelet ...
