CONVERSION OF ENTANGLEMENT BETWEEN CONTINUOUS VARIABLE AND QUBIT SYSTEMS VIA INTERACTION
Xiaoyu Chen, Li-zhen Jiang · International Journal of Quantum Information · 2008
We investigate how entanglement can be transferred between continuous variable and qubit systems. We find that a two-mode squeezed vacuum state and a continuous variable Werner state can be converted to the product states of an infinitive number of two-qubit states while keeping the entanglement. The reverse process is also possible. The proposed conversion model is theoretically viable but difficult to realize in the laboratory.
