Exploring the possibility of a complex-valued non-Gaussianity measure for quantum states of light
Andrew J. Pizzimenti, Prajit Dhara, Zacharie Van Herstraeten +2
We consider a quantity that is the differential relative entropy between a generic Wigner function and a Gaussian one. We prove that said quantity is minimized with respect to its…
