Stellenbeschreibung

Place of Employment: Aachen
Start Date: To the next possible Date
Working Hours: 39 Hours / Week
Salary: Pay group 13 - 14 of TVöD-Bund
Application Deadline: The position will be published until it is successfully filled

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 demonstrations 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
