Conditions for manipulation of a set of entangled pure states
Chuan-Wei Zhang, Chuan-Feng Li, Guang-Can Guo
We derive a sufficient condition for a set of pure states, each entangled in two remote -dimensional systems, to be transformable to -dimensional-subspace equivalent entangle…

Universal Quantum Entanglement Concentration Gate
Zi-Yang Wang, Chuan-Wei Zhang, Chuan-Feng Li +1
We construct a Universal Quantum Entanglement Concentration Gate (QEC-Gate). Special times operations of QEC-Gate can transform a pure 2-level bipartite entangled state to nearly m…
