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…
Monogamy relation in multipartite continuous-variable quantum teleportation
Jaehak Lee, Se-Wan Ji, Jiyong Park +1
Quantum teleportation (QT) is a fundamentally remarkable communication protocol that also finds many important applications for quantum informatics. Given a quantum entangled resou…
Continuous-variable dense coding via a general Gaussian state: Monogamy relation
Jaehak Lee, Se-Wan Ji, Jiyong Park +1
We study a continuous variable (CV) dense-coding protocol, originally proposed to employ a two-mode squeezed state, using a general two-mode Gaussian state as a quantum channel. We…
Gaussian states under coarse-grained continuous variable measurements
Jiyong Park, Se-Wan Ji, Jaehak Lee +1
The quantum-to-classical transition of a quantum state is a topic of great interest in fundamental and practical aspects. A coarse-graining in quantum measurement has recently been…
Generating arbitrary photon-number entangled states for continuous-variable quantum informatics
Su-Yong Lee, Jiyong Park, Hai-Woong Lee +1
We propose two experimental schemes that can produce an arbitrary photon-number entangled state (PNES) in a finite dimension. This class of entangled states naturally includes non-…
