Entangled multiplet by angular momentum addition
Hyuk-jae Lee, Sung Dahm Oh, Doyeol Ahn
We present the visible entangled states of 4-qubit system which can be observed easily in physical laboratories. This was motivated from the fact that the entangled state of 2-qubi…
Relativistic entanglement and Bell's inequality
Doyeol Ahn, Hyuk-jae Lee, Young Hoon Moon +1
In this paper, the Lorentz transformation of entangled Bell states seen by a moving observer is studied. The calculated Bell observable for 4 joint measurements turns out to give a…
Relativistic entanglement of quantum states and nonlocality of Einstein-Podolsky-Rosen(EPR) paradox
Doyeol Ahn, Hyuk-jae Lee, Sung Woo Hwang
Relativistic bipartite entangled quantum states is studied to show that Nature doesn't favor nonlocality for massive particles in the ultra-relativistic limit. We found that to an…
Lorentz covariant reduced-density-operator theory for relativistic quantum information processing
Doyeol Ahn, Hyuk-jae Lee, Sung Woo Hwang
In this paper, we derived Lorentz covariant quantum Liouville equation for the density operator which describes the relativistic quantum information processing from Tomonaga-Schwin…
