What is special about the Kirkwood-Dirac distributions? Only they produce natural conditional expectations
Matéo Spriet, Christopher Langrenez, Raymond Brummelhuis +1
Among the many quasiprobability representations of quantum mechanics, the family of Kirkwood-Dirac (KD) representations has come to the foreground in recent years. Each such KD rep…

Characterizing the Kirkwood-Dirac positivity on second countable LCA groups
Matéo Spriet
We define the Kirkwood-Dirac quasiprobability representation of quantum mechanics associated with the Fourier transform over second countable locally compact abelian groups. We dis…
