My current work focuses on silicon double quantum dots and their use in quantum information processing (QIP). In this context I am researching novel ways of implementing QIP architectures in silicon: definition of qubits, their initialisation, manipulation and readout, as well as exploring ways to simplify scalable QIP architectures. I am also interested in other low dimensional systems, such as nanowire FETs and graphene, as well as their microwave and noise properties.
Recent Research projects
I am currently contributing to the EU-funded TOLOP project (www.tolop.eu), which aims to find novel concepts and devices for future low-power computing. Here, I am investigating the RF and low temperature properties of silicon nanowire FETs, as well as their use in QIP.
