Summer internship on Optimizing Noise Filtering for Robust Qubits

We are looking for a motivated summer intern to join a collaborative project aimed at improving the performance of superconducting qubits by optimizing noise filtering in dilution‑refrigerator setups.

Information about the division and project

The Department of Microtechnology and Nanoscience advances the frontiers in quantum technology, nanoscience, photonics and future electronic systems - for technical and societal development. Our cross-disciplinary approach gives interesting collaborations in academy, industry and society, and is a driving force for innovations, results and breakthroughs. We offer a vibrant, international research environment and direct access to world-class nanofabrication facilities. 

At the Quantum Technology Laboratory, we explore how quantum physics can unlock radically new ways of processing information - far beyond the limits of classical systems. Our research spans quantum computing, sensing, transduction, thermodynamics, and foundations, all aimed at harnessing the powerful behavior of light and matter at the quantum level. We offer a vibrant, international research environment and direct access to world-class nanofabrication facilities. 

Superconducting transmon qubits are highly sensitive to thermal noise entering through their control lines, even inside millikelvin refrigerators. This project models how noise from different temperature stages combines into a nonthermal environment seen by the qubit. Using Redfield theory, you will study how attenuation and filtering choices affect relaxation and decoherence.
The aim is to find attenuation strategies that reduce harmful noise while keeping the control signal strong enough.

Job description

• Modelling of open quantum systems and nonthermal environments
• Physics of superconducting qubits and quantum coherence
• Practical aspects of microwave control lines and dilution refrigerators
• Collaboration across theoretical and experimental teams

Qualifications

To qualify for this position, we believe you:

• Are a student in physics, applied physics, electrical engineering, or a related field
• Are interested in quantum technology, quantum information, or condensed‑matter physics
• Have basic programming experience. Python, MATLAB, or similar is an advantage
• Are curious and motivated to learn
  
  

Contract terms
Temporary employment with a start date as soon as possible, ending end of August.
