摘要：

We show that oriented nanostructures from single molecules of a conducting polymer act as highly robust room-temperature single-photon sources. Individual z-oriented polymer nanostructures show high-contrast photon antibunching with a modulation depth exceeding 90%. These results suggest the feasibility of a "push-button" technology for polymer-based single-photon sources in photonic-based quantum information processing applications.
