Abstract
We use a new formulation of nonclassicality in weak measurements based on the probabilistic behavior of “weak quasimoments” to show that nonclassical quantum states in the Glauber–Sudarshan representation can behave classically in weak measurements with post-selection. We directly calculate marginal quasidistributions related to the “weak quasimoments” and show that they are nonnegative.
