摘要
We report an ultrafast downconversion quantum interface, where 910-nm single photons from a quantum dot are downconverted to the 1.5-mu m telecom band with sub-10 picosecond pulses at 2.2-mu m, enabling the demonstration of quantum-dot spin-photon entanglement. (C) 2013 Optical Society of America
