N2 - Photonic graph states are underlying resources for one-way optical
quantum computation, quantum error correction, fundamental testing of
quantum mechanics, and quantum communication networks. Most existing
works, however, are based on the spontaneous parametric down-conversion
sources that intrinsically suffer from probabilistic generation and
double pair components. Here, we create two important classes of graph
states, a polarization-encoded four-photon Greenberger–Horne–Zeilinger
(GHZ) state and a linear cluster state, by actively demultiplexing a
deterministic single-photon source from a semiconductor quantum dot
embedded in a micropillar. A state fidelity of 0.790 ± 0.009 (0.763 ±
0.004) and a count rate of ∼13 Hz are observed for the four-photon GHZ
(cluster) state. The results constitute a new route toward the
multiphoton entanglement with deterministic single-photon sources.
