Wigner function negativity in a classical model of quantum light
Brian R. La Cour
The presence of negative values in the Wigner quasiprobability distribution is deemed one of the hallmarks of nonclassical phenomena in quantum systems. Here we demonstrate a class…

Pinching operators for approximating multiphoton entangled states
Skylar R. Turner, Brian R. La Cour
We introduce the pinching operator, which extends the theory of squeezing operators to non-Gaussian operators, and use it to approximate -photon entangled states using a pinched…
