Quantum Secure Communication with W States
Jaewoo Joo, Jinhyoung Lee, Jingak Jang +1
A W state is pair-wisely entangled, belonging to the different class from Greenberger, Horne, and Zeilinger (GHZ) state. We show that the W state enables three variant protocols, t…

A scheme for direct observation of entanglement for Gaussian continuous variables
M. S. Kim, Jinhyoung Lee
We suggest an experimentally realizable scheme to test entanglement of a mixed Gaussian continuous variable state. We find that the entanglement condition is simplified for the fam…
