At the 558th Dies Academicus, the Emilie Louise Frey-Preis 2018 is awarded to Katharina Laubscher for her Master thesis "Universal quantum computation using a hybrid quantum double model” carried out in the group of Prof. Daniel Loss.
Currently, Katharina is an Excellence Fellow of the PhD School “Quantum Computing and Quantum Technologies” and is doing her PhD in the group of Prof. Jelena Klinovaja in the field of topological quantum computing.
In her Master thesis, Katharina showed that it is possible to build novel planar quantum codes based on the combination of two different quantum double models, and that such hybrid codes constitute a novel pathway to universal fault-tolerant quantum computation. From a purely theoretical point of view, this is an important proof of principle and a large step towards a complete understanding of the quantum double models and their potential for quantum computation. From a more practical point of view, there may be direct advantages in terms of time- and special overhead of such a hybrid model compared to other techniques that enable universal fault-tolerant quantum computation, the most prominent one being a particularly resource-intensive procedure called magic state distillation.
