  Collision is a useful tool for revealing quantum effects and realizing
quantum informational tasks. We demonstrate that repeated collisions by
itinerant electrons can dissipatively drive two remote spin qubits into an
entangled state in a generic collisional framework. A coherent spin exchange
with either qubit facilitates entanglement generation. When combined with
proper local driving, these collisions induce an entangled steady state in most
collision configurations. Particularly, the collision which is symmetric for
the two qubits results in a unique steady state close to a maximally entangled
state. Due to the dissipative nature of the process, the entanglement persists
in the presence of decoherence, provided the collision frequency exceeds the
decoherence rate. Our model can be experimentally implemented using
single-electron sources.
