Quantifying non-Gaussianity of a quantum state by the negative entropy of quadrature distributions
Jiyong Park, Jaehak Lee, Kyunghyun Baek +1
We propose a non-Gaussianity measure of a multimode quantum state based on the negentropy of quadrature distributions. Our measure satisfies desirable properties as a non-Gaussiani…

Fundamental limits on concentrating and preserving tensorized quantum resources
Jaehak Lee, Kyunghyun Baek, Jiyong Park +2
Quantum technology offers great advantages in many applications by exploiting quantum resources like nonclassicality, coherence, and entanglement. In practice, an environmental noi…
