Violation of Bell inequality by four photon Greenberger Horne Zeilinger state with a phase from a warm atomic ensemble
Jiho Park, Junghee Ryu, Heonoh Kim +1
A Greenberger Horne Zeilinger (GHZ) entangled state with a phase is crucial for realizing desired multipartite quantum states for practical applications. Here, we report violations…

Inseparability Criterion Using Higher-Order Schrödinger-Robertson Uncertainty Relation
Chang-Woo Lee, Junghee Ryu, Jeongho Bang +1
We formulate an inseparability criterion based on the recently derived generalized Schrödinger-Robertson uncertainty relation (SRUR) [Ivan {\it et al.} J. Phys. A :Math. Theor. {\b…
