PhD Candidate Quantum

Your role

Your mission is to advance research in quantum technologies by joining the Wallenberg Quantum Centre as a PhD candidate registered at Chalmers University of Technology (Sweden) while being employed by Atlas Copco Group on a 4-year contract. This role is part of Atlas Copco's Scientific Vacuum Division quantum strategy, focusing on superconducting qubit generation - a critical technology for scalable quantum computing.

Quantum computers require extremely low cryogenic temperatures to operate efficiently, achieved through Helium Dilution Refrigerators (HDR). Atlas Copco equipment plays a vital role in HDR systems, particularly in the closed-cycle recirculation of ³He/⁴He mixtures. Your work will help build a fundamental understanding of HDR operational characteristics, enabling future scalability and efficiency of quantum hardware infrastructure.

As a PhD candidate in Quantum Technology you will report to the Global Application Manager of the Scientific Vacuum Division who will serve as your industry thesis advisor. You will be appointed a primary academic thesis supervisor from Chalmers University.

Your role:

Develop advanced simulation models for ³He/⁴He ratios and flow characterization in vacuum and compression stages.Measure and analyze HDR performance across different operational stages (PT1/PT2, Still, Mixing Chamber, Cold Plates) under various conditions.Characterize new vacuum and cryogenic equipment under development in similar operational environments.Investigate equipment behavior influencing qubit performance, including contamination effects, environmental factors, and reliability aspects.Execute experiments using HDR equipment at Chalmers University and support safe hardware installations.Build expertise in vacuum and cryogenic physics through structured training and safety courses.Gain proficiency in Atlas Copco's modeling tools and industry-standard software (Comsol, Monte Carlo, and Janus - successor to Pascal and PumpCalc). To succeed, you will need
