Abstract: | When the time variable in quantum signal processing is discrete,
the Fourier transform exists on the vector space of n-tuples over the Galois field F2, which plays an important role in the
investigation of quantum signals. By using Fourier transforms, the
idea of quantum coding theory can be described in a setting that
is much different from that seen that far. Quantum BCH codes can
be defined as codes whose quantum states have certain specified
consecutive spectral components equal to zero and the
error-correcting ability is also described by the number of the
consecutive zeros. Moreover, the decoding of quantum codes can be
described spectrally with more efficiency. |
