Postdoctoral Researcher or PhD Candidate (Quantum Technology, Superconducting Qubits) | Postdoc oder Doktorandin / Doktorand (m/w/d) Quantentechnologie, supraleitende Qubits (25-210-2B)

Job Summary

The Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig is seeking a Postdoctoral Researcher or PhD Candidate to join the Quantum Electronics division, focusing on the fabrication and characterization of superconducting quantum circuits. This high-tech research role involves performing complex measurements on superconducting qubits within a dilution cryostat at millikelvin temperatures, often incorporating internally developed parametric amplifiers. Key responsibilities include the continuous refinement and optimization of both measurement hardware (e.g., mK sample holders and filter concepts) and control software, primarily based on Python. The successful candidate will actively support the first European inter-laboratory comparison of superconducting qubit measurements, requiring strong experimental aptitude and analytical skills. This position offers the opportunity to conduct cutting-edge research, publish scientific results, and contribute to international metrology standards within a highly collaborative and innovative environment.
