Entanglement of Gaussian states using beam splitter
Rabia Tahira, Manzoor Ikram, Hyunchul Nha +1
We study an experimental scheme to generate Gaussian two-mode entangled states via beam splitter. Specifically, we consider a nonclassical Gaussian state (squeezed state) and a the…
Quantum Teleportation of Light
Changsuk Noh, A. Chia, Hyunchul Nha +2
Requirements for the successful teleportation of a beam of light, including its temporal correlations, are discussed. Explicit expressions for the degrees of first- and second-orde…
Uncertainty inequalities as entanglement criteria for negative partial-transpose states
Hyunchul Nha, M. Suhail Zubairy
In this Letter, we show that the fulfillment of uncertainty relations is a sufficient criterion for a quantum-mechanically permissible state. We specifically construct two pseudo-s…
Complete conditions for legitimate Wigner distributions
Hyunchul Nha
Given a real-valued phase-space function, it is a nontrivial task to determine whether it corresponds to a Wigner distribution for a physically acceptable quantum state. This topic…
Linear optical scheme to demonstrate genuine multipartite entanglement for single-particle W states
Hyunchul Nha
We consider the method of entanglement witness operator to verify genuine multipartite entanglement for single-particle W states involving N parties. In particular, linear optical…
