Hybrid quantum technology
The controlled interfacing of individually well-isolated atoms is one of the outstanding challenges for bottom-up assemblies of complex quantum systems. In our research, we build on quantum emitters in a nanometer-sized host matrix and utilize AFM-based nano-manipulation to establish controlled evanescent coupling. In this approach classical photonics and plasmonic devices can be post-processed with quantum functionality. Our work is targeted to develop complex quantum systems in a bottom-up approach.
