Sven Ramelow studied physics at the Humboldt University in Berlin, focusing on optics, semiconductor and computational physics. His studies included a 10 month stay in Australia, where he studied at Melbourne University and he worked in the MARC group, the Melbourne node of the Centre for Quantum Computer Technology. Having returned he finished his diploma thesis about single photons and quantum dots for quantum computation with the Group of Prof. Oliver Benson. In his PhD project in Prof. Anton Zeilinger's group he now works on single photon upconversion (SPUC) to enhance quantum key distribution in fibre networks.
