Development of a low temperature all-fiber resonator platform with integrated Eu3+:Y203 nanocrystals

Tobias Krom
KIT Karlsruhe

Rare earth ions as a dopant in nanocrystals are promising candidates for quantum information processing. The long coherence time of their nuclear spin and their optical interface are adequate for quantum networking. In my talk I report on the development of an optical resonator platform out of two machined optical fibers. This platform paths the way for single qubit control and readout. The presented work handles the crucial problem of the integration of a nanocrystal into an all-fiber cavity.
