Quantum computing is expected to power the next revolution in science. A quantum computer operates on 'qubits' (quantum bits), who's quantummechanical properties allow to perform computing tasks that are not possible with classical digital computers. These qubits however only operate when cooled down to temperatures as low as 20 milli-Kelvin. That is colder than outer space, and needs a special dilution refrigerator.
Apart from the complex physics and material science involved in fabricating qubits, they also need to be controlled by custom-designed electronic circuits. This thesis focusses on these control circuits. The performance of standard CMOS transistors must be characterized for modelling at such low temperatures. Collaboration with imec's expert in quantum physics and device technology will allow to define an architecture and set requirements on the building blocks. Implementation of these building blocks will consist of the typical circuit design cycle including literature review, schematic simulation and layout. Knowledge of analog design basics, and Cadence/spectre tools is a must.
