| 1 | Complete temporal characterization of a single photon显示文摘Precise information about the temporal mode of optical states is crucial for optimizing their interaction efficiency between themselves and/or with matter in various quantum communication devices.Here we propose and experimentally demonstrate a method of determining both the real and imaginary components of a single photon’s temporal density matrix by measuring the autocorrelation function of the photocurrent from a balanced homodyne detector at multiple local oscillator frequencies.We test our method on single photons heralded from biphotons generated via four-wave mixing in an atomic vapor and obtain excellent agreement with theoretical predictions for several settings. | Zhongzhong Qin Adarsh S Prasad Travis Brannan Andrew MacRae A Lezama AI Lvovsky | 2015 | Light(Science & Applications)2015，4，1： | 1 |
