The JARA-Institute for Quantum Information (JARA-QI), headed by David DiVincenzo and Hendrik Bluhm conducts theoretical research on many aspects of quantum computing and experimental research on semiconductor qubits. The institute has two parts, located at the sites Forschungszentrum Jülich GmbH and RWTH Aachen University, under the umbrella of the Jülich-Aachen Research Alliance (JARA). In the domain of semiconductor qubits, the development and validation of an advanced architecture based on coherent long range qubit shuttling is currently one of our main activities. To this end, we pursue a holistic approach addressing material challenges, device simulation, fabrication, systematic characterization, high fidelity operation as well as integration and scaling technologies. Our ultimate vision is a fully integrated semiconductor processor with integrated low-power control circuits to enable a scale up to millions of qubits. https://www.youtube.com/watch?v=0tWaplC4FVs
Your Job:
Building on in-house fabricated devices, we have recently demonstrated the ability to shuttle electrons between gate defined quantum dots in Si/SiGe over micron-scale distances using only four different AC-voltages, independent of the distance covered https://arxiv.org/abs/2108.00879 . Theoretical consideration indicate good prospects for maintaining spin-coherence of the shuttled electron, which would make this approach very promising for scaling up semiconductor spin qubit devices. This position focuses on experimentally demonstrating coherent spin shuttling, shuttling-compatible high-fidelity qubit control and further ingredients for a shuttling-based architecture, using devices from academic or industrial fabrication.
