Postdoc - scalable, shuttle-based spin-qubit quantum-chips
The JARA-Institute for Quantum Information (PGI-11) 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 our advanced
architecture based on coherent long range qubit shuttling Nat. Commun. 15,
4977 (2024) 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.

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
20 micron-scale distances using only four different AC-voltages, independent
of the distance covered Nat. Commun. 15, 2296 (2024).
Theoretical consideration and experimental demostrations indicate good
prospects for maintaining spin-coherence of the shuttled electron Nat.
Commun. 15, 1325 (2024) which makes this approach very promising for
scaling up semiconductor spin qubit devices Nature 653, 360 (2026). 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. Key activities can include:
Experimental characterization of spin coherence during shuttling
Shuttling-compatible demonstration of high-fidelity qubit control
Demonstration of shuttle-based Si/SiGe quantum chips
Advancement of large-scale shuttling based architecture with
2D-connectivity
Migration to industrially fabricated devices
Your Profile
Master and PhD in physics or a related field
In-depth experience with quantum control experiments on quantum dot qubits
Good software development skills
Experience with sub-Kelvin cryogenic techniques
Strong aptitude for mentoring students
Good communication skills
A strong drive to conduct ambitious, cutting edge research towards
scalable quantum computing
A research track record commensurate with our ambition
Very good command of written and spoken English with extensive vocabulary
is required (at least B2 level according to the CEFR), ideally supported
by a certificate confirming the language level. Knowledge of the German
language is not mandatory but certainly appreciated
