In the scheme, A-type atoms pass a resonatorlike equipment of dispersing and absorbing macroscopic bodies giving rise to body-assisted electromagnetic field resonances of well-defined heights and widths. Strong atom-field coupling is combined with weak atom-field coupling to realize entanglement transfer from the dipole-allowed transitions to the dipole-forbidden transitions, whereby the entanglement is preserved when the atoms depart from the bodies and from each other. The theory is applied to the case of atoms passing by a microsphere.EnglishAtomic systemsMicrosphereQuantum-information processingReservoir engineeringThree-level atomsIon exchangeMagnetic field effectsMathematical modelsMicroscopic examinationPhotonsQuantum theoryResonatorsAtomic physicsArticle10.1103/PhysRevA.71.032326
