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…
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…
Single-photon quantum nonlocality: Violation of the Clauser-Horne-Shimony-Holt inequality using feasible measurement setups
Su-Yong Lee, Jiyong Park, Jaewan Kim +1
We investigate quantum nonlocality of a single-photon entangled state under feasible measurement techniques consisting of on-off and homodyne detections along with unitary operatio…
