  • Entanglement Swapping with Semiconductor-Generated Photons Violates Bell’s Inequality 
    Zopf, Michael; Keil, Robert; Chen, Yan; Yang, Jingzhong; Chen, Disheng; Ding, Fei; Schmidt, Oliver G. (College Park, MA : American Physical Society, 2019)
    Transferring entangled states between photon pairs is essential in quantum communication. Semiconductor quantum dots are the leading candidate for generating polarization-entangled photons deterministically. Here we show ...
  • Frequency feedback for two-photon interference from separate quantum dots 
    Zopf, Michael; Macha, Tobias; Keil, Robert; Urunuela, Eduardo; Chen, Yan; Alt, Wolfgang; Ratschbacher, Lothar; Ding, Fei; Meschede, Dieter; Schmidt, Oliver G. (College Park : American Physical Society, 2018)
    We employ active feedback to stabilize the frequency of single photons emitted by two separate quantum dots to an atomic standard. The transmission of a rubidium-based Faraday filter serves as the error signal for frequency ...
