Quantum Computing

Objective

In this topic we strive for system solutions of future universal quantum computers. Intermediate demonstartors show the potential for the long-term scientific challenges ranging from scalable system concepts to System-on-Chip (SoC) implementations providing all control and readout functions at temperatures down to almost 0 Kelvin (-273.15 °C). All developments are driven top-down from the application and implemented bottom-up in accordance with industrial quality standards.

Quantum Computing Hardware Systems

Our research focuses on the design and modelling of hybrid quantum computing hardware systems. The overall vision is a universal quantum computer, and we are exploring how to build scalable classical-quantum mechanical systems that strive towards this goal.

Automated Embedded Qubit Tuning

The focal point of our research endeavors lies in the automated tuning of qubits through the use of cryogenic electronics developed within our institute. Tuning refers to the preceding highly complex steps required for the spin-qubit operation.

Cryogenic Qubit Readout and Control

Our research and development activities are focused on innovative cryogenic electronics that can address the wiring bottleneck associated with the scaling of quantum computers. This approach brings classical control and readout electronics in direct vicinity to the quantum bits and down to the milli-Kelvin temperature stage.

Measurement Process Optimization

We verify and validate highly integrated circuits developed within our institute or provided by external partners within collaboration projects. Next to state-of-the-art electrical measurement equipment, we combine these with cryostats to enable device, circuit and system level characterization of the electronics at temperatures down to 10 Millikelvin, either stand-alone or in combination with semiconductor or superconducting qubits.
