Non-Gaussianity and entropy-bounded uncertainty relations: Application to detection of non-Gaussian entangled states
Kyunghyun Baek, Hyunchul Nha
We suggest an improved version of Robertson-Schrödinger uncertainty relation for canonically conjugate variables by taking into account a pair of characteristics of states: non-Gau…

Faithful measure of Quantum non-Gaussianity via quantum relative entropy
Jiyong Park, Jaehak Lee, Kyunghyun Baek +2
We introduce a measure of quantum non-Gaussianity (QNG) for those quantum states not accessible by a mixture of Gaussian states in terms of quantum relative entropy. Specifically,…

Entropic uncertainty relations for successive generalized measurements
Kyunghyun Baek, Wonmin Son
We derive entropic uncertainty relations for successive generalized measurements by using general descriptions of quantum measurement within two {distinctive operational} scenarios…
