Analysis of radiatively stable entanglement in a system of two dipole-interacting three-level atoms
Igor Bargatin, B. A. Grishanin, Victor N. Zadkov · Physical Review A · 2000
We explore the possibilities of creating radiatively stable entangled states of two three-level dipole-interacting atoms in a \ensuremath{\Lambda} configuration by means of laser biharmonic continuous driving or pulses. We propose three schemes for generation of entangled states which involve only the lower states of the \ensuremath{\Lambda} system, not vulnerable to radiative decay. Two of them employ coherent dynamics to achieve entanglement in the system, whereas the third one uses optical pumping, i.e., an essentially incoherent process.
