Surface plasmon polaritons (plasmons) have the potential to interface electronic and optical devices. They could prove extremely useful for integrated quantum information processing. Here we demonstrate on-chip electrical detection of single plasmons propagating along gold waveguides. The plasmons are excited using the single-photon emission of an optically emitting quantum dot. After propagating for several micrometers, the plasmons are coupled to a superconducting detector in the near-field. Correlation measurements prove that single plasmons are being detected.
表面等离激元（等离子体）具有连接电子和光学器件的潜力。它们在集成量子信息处理方面可能非常有用。在这里，我们演示了在金波导上传播的单个等离子体的片上电检测。等离子体是使用光学发射量子点的单光子发射来激发的。传播几微米后，等离子体在近场中与超导探测器耦合。相关测量证明正在检测单个等离子体。
