Non-Gaussian entanglement criteria for atomic homodyne detection
Jaehak Lee, Jiyong Park, Jaewan Kim +2
Homodyne measurement is a crucial tool widely used to address continuous variables for bosonic quantum systems. While an ideal homodyne detection provides a powerful analysis, e.g.…
Comment on "Multiparty quantum mutual information: An alternative definition"
Jaehak Lee, Gibeom Noh, Changsuk Noh +1
We show that, contrary to the claim by Kumar [Phys. Rev. A 96, 012332 (2017)], the quantum dual total correlation of an -partite quantum state cannot be represented as the quant…
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…
Quantum non-Gaussianity and secure quantum communication
Jaehak Lee, Jiyong Park, Hyunchul Nha
No-cloning theorem, a profound fundamental principle of quantum mechanics, also provides a crucial practical basis for secure quantum communication. The security of communication c…
