|| JARA-Institute for Quantum Information (PGI-11), member of the Peter Grünberg Institute, is focusing on theoretical and experimental development of large-scale quantum computing system. Yet, the institute is the member of the OpenSuperQ consortium (http://www.opensuperq.eu) with its main objective to design, build an operate a quantum information processing system based on superconducting quantum circuits reaching the scale of 100 qubits.
We are offering a
PhD position - “Experimental superconducting quantum computing”
Superconducting cubits are considered today as the most real and feasible approaches to the development of multi-qubit quantum computer. Most of us have read news about “quantum supremacy” recently demonstrated by Google, where the successful demonstration was made with the system consisting of 53 transmon qubits. Physically, these transmons are just electrical non-linear circuit nanofabricated by utilizing very thin aluminium film, which becomes superconducting at temperatures below 1 Kelvin. In contrast to the other well known quantum information platforms such as spins in solids, quantum dots, nitrogen-vacancies in diamond and trapped ion, where the quantum information is encoded in natural microscopic degrees of freedom, superconducting qubits are macroscopic in size (~1mm), lithographically defined and offers a plenty of flexibilities in engineering of their properties. Our work initially aims at the setting up the millikelvin cryogenic system, development of microwave control and readout electronics, preparation of the measurement/data processing software and enabling the remote control of all instruments. We finally aim at the demonstration of the fully-functional, working and accessible multi-qubit quantum processing platform with the-state-the-art performance.
Yet, with a cooperation involving local research groups we plan to establish reliable fabrication of superconducting quantum circuits in FZ Jülich with the state-of-the-art performance in terms of coherence, gate fidelities and gate errors.
