Group Covariant Signals in Quantum Information Theory

  • Chapter
Quantum Communication, Computing, and Measurement 2

Abstract

Necessary and sufficient condition for group covariant signals is given. This condition shows what kind of signals correspond to “group covariant signals.” We show by applying this condition that many signals, such as arbitrary binary signals, PPM, FSK, and PSK coherent-state signals, equidistant codes, and binary linear codes, are all group covariant.
