Discrete Wigner Functions from Informationally Complete Quantum Measurements
John B. DeBrota, Blake C. Stacey
Wigner functions provide a way to do quantum physics using quasiprobabilities, that is, "probability" distributions that can go negative. Informationally complete POVMs, a much you…

Lüders Channels and the Existence of Symmetric Informationally Complete Measurements
John B. DeBrota, Blake C. Stacey
The Lüders rule provides a way to define a quantum channel given a quantum measurement. Using this construction, we establish an if-and-only-if condition for the existence of a …
