  We propose a heralded quantum repeater protocol based on the general
interface between the circularly polarized photon and the quantum dot embedded
in a double-sided optical microcavity. Our effective time-bin encoding on
photons results in the deterministic faithful entanglement distribution with
one optical fiber for the transmission of each photon in our protocol, not two
or more. Our efficient parity-check detector implemented with only one
input-output process of a single photon as a result of cavity quantum
electrodynamics makes the entanglement channel extension and entanglement
purification in quantum repeater far more efficient than others, and it has the
potential application in fault-tolerant quantum computation as well. Meanwhile,
the deviation from a collective-noise channel leads to some phase-flip errors
on the nonlocal electron spins shared by the parties and these errors can be
depressed by our simplified entanglement purification process. Finally, we
discuss the performance of our proposal, concluding that it is feasible with
current technology.
