CONCENTRATION FOR ATOMIC ENTANGLEMENT STATES VIA CAVITY DECAY
Gang Zhang, Ming Yang, Zheng‐Yuan Xue, Zhuo‐Liang Cao · International Journal of Quantum Information · 2006
We present a physical scheme for entanglement concentration of atomic entangled states via cavity QED. In our scheme cavity decay and atomic spontaneous emission are taken into consideration, and the atomic qubit is used as stationary qubit and photonic qubit as flying qubit, thus it is more practical to discuss entanglement concentration.
