Entanglement reciprocation between atomic qubits and entangled coherent state
Zhou, L, Yang, G H · CERN Document Server (European Organization for Nuclear Research) · 2006
Introducing classical fields, we can transfer entanglement completely from discrete qubits into entangled coherent state. The entanglement also can be retrieved from the continuous-variable state of the cavities to the atomic qubits. Via postselection measure, atomic entangled state and entangled coherent state can be mutual transformed fully.
