RF, mm-wave and THz circuits 
Quantum and cryogenic circuits The research regarding quantum computers received a lot of momentum last years. An unsolved problem stays the integration of a large number (>10 000) of qubits. A first step to facilitate the integration of multiple qubits is to integrate the electronics as close as possible to the qubits, this way the bulky external wiring can be eliminated. Based on the available cooling power, the electronics are often placed at the 4K stage. In this situation, mostly oscillators with an oscillation frequency around the 8-12 GHz are used to manipulate the qubits situated at the mK temperature stage.
The aim of this research is to increase the oscillator frequency to mm-wave frequencies such that qubits that are working at the 4K (or higher) temperature stage can be manipulated. By placing the whole system at higher temperatures, a lot of power could be saved.
