Poster presented at the International Conference on
Quantum Information Processing and Communication QIPC. Zurich - Switzerland, Sep. 5-9, 2011. Abstract: Heralded qubit ampli cation has been proposed as a means of realising device independent quantum key distribution [1]. Such an ampli er, based on a quantum scissors scheme [2, 3], have been done for coherent states [4, 5]. We have studied the feasibility of an ampli er for polarization qubits, and used it as the basis for a qutrit teleportation experiment. The poster presented our results at the moment in this direction. [1] Nicolas Gisin et al., PRL 105, 070501 (2010)
