As part of the RaIQu (Radiowave Integrated Qubit Control) project, there is an international mobility project between the Ishikuro Laboratory at Keio University and the Institute for CMOS Design at TU Braunschweig. The core aspect of the cooperation is to enable young academics at all levels (students, doctoral candidates and professors) to research and teach at an international level on highly complex challenges in quantum electronics.
The technical focus of the project is on the research and development of novel, highly integrated bipolar and field-effect transistor-based chips for controlling qubits. The frequency range of the control electronics depends on the realization of the qubit technology and will cover a spectrum of more than 12 GHz within the scope of this international cooperation.In order to enable hybrid integration, the developed circuits are operated at a temperature of 4 K. This enables a considerable miniaturization (reduction by 8 orders of magnitude) of the high-frequency electronics currently used to control quantum gates. The hybrid-integrated approach of qubit control electronics is the key to the scalability of a quantum computer.
As part of this highly complex research topic, the project partners are focusing on international exchange and collaboration. The synergy between the Ishikuro Laboratories and the Institute for CMOS Design is maximized at all levels. The qubit control systems being developed as part of RaIQu are highly modular and consist of individual sub-blocks with varying degrees of complexity in their design, depending on their function. This is an ideal prerequisite for assigning both undergraduate and postgraduate students a task appropriate to their level of knowledge. This enables young doctoral students to spend up to 6 months and Master's students up to 3 months at the respective partner institute for research purposes. Active research at the respective partner institutes ensures the production of the designed circuits and provides a solid basis for publishing the research results at internationally recognized conferences and journals.
