Quantifying non-Gaussianity of quantum-state correlation
Jiyong Park, Jaehak Lee, Se-Wan Ji +1
We consider how to quantify non-Gaussianity for the correlation of a bipartite quantum state by using various measures such as relative entropy and geometric distances. We first sh…
Practical resources and measurements for lossy optical quantum metrology
Changhun Oh, Su-Yong Lee, Hyunchul Nha +1
We study the sensitivity of phase estimation in a lossy Mach-Zehnder interferometer (MZI) using two general, and practical, resources generated by a laser and a nonlinear optical m…
Optimal continuous-variable teleportation under energy constraint
Jaehak Lee, Jiyong Park, Hyunchul Nha
Quantum teleportation is one of the crucial protocols in quantum information processing. It is important to accomplish an efficient teleportation under practical conditions, aiming…
Revealing nonclassicality beyond Gaussian states via a single marginal distribution
Jiyong Park, Yao Lu, Jaehak Lee +6
A standard method to obtain information on a quantum state is to measure marginal distributions along many different axes in phase space, which forms a basis of quantum state tomog…
