QUANTUM COMPUTING HARDWARE SYSTEMS

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.

Optimized hardware is essential for operating the millions of qubits required for a universal quantum computer. As quantum mechanical and classical hardware properties are interdependent, our holistic approach to designing and optimizing hardware systems is an important element of quantum computing research.

For the classical hardware, we specialize in cryogenic integrated architectures as a key feature for scalability and work primarily with architectures for SiGe spin qubits, but we are also investigating other qubit implementations.

Research Topics

  • Co-Simulation framework to simulate (cryogenic) integrated circuits, quantum mechanical devices and electronic models to optimize the system performance
  • Electronics architecture modeling for scalable qubit operation of SiGe spin qubits
