KW - Quantum Entanglement, Spontaneous Emission, Photon Exchange.
AB - <p style="text-align: justify;">We report possibility of generating entanglement between two atoms in free
space when their spatial separation is on the order of wavelength or less. We show that
these two atoms get coupled by photon exchange due to spontaneous decay, which in
turn generates the atomic entanglement. By introducing the incoherent pumping, one
can obtain the steady entanglement, and the incoherent pumping can overcome the
decay of the atoms. Moreover, one can obtain the larger value of steady entanglement
via proper tuning the incoherent pumping.</p>
