Join our innovative theory team and contribute to exciting research in scaling up quantum computers in a collaborative and dynamic environment.
About us
Department of Microtechnology and Nanoscience conducts leading research in quantum technology, nanoscience, photonics, and future electronic systems, contributing to both technological and societal development. We offer a vibrant, international research environment with strong cross-disciplinary collaborations and direct access to world-class nanofabrication facilities.
This project is part of the Wallenberg Centre for Quantum Technology , a 12-year, 1.5-billion-SEK national initiative launched in 2018 to position Sweden at the forefront of quantum technology and to develop a Swedish quantum computer. The WACQT team at Chalmers comprises around 100 researchers from multiple disciplines, including physics, engineering, computer science, and materials science. The work focuses on developing superconducting quantum devices, control circuits, firmware, and methods in close collaboration between experimental and theoretical research groups. Theoretical efforts support hardware modelling and the development of application use cases for the quantum processor.
About the research project
Our ambitious goal at Chalmers is to build a quantum computer with 100 superconducting qubits and to apply it to real computational problems that cannot be efficiently solved on a conventional computer. To achieve this goal, our theory team is developing methods to model, design, and characterize large-scale quantum devices. In this research project, the focus will be on characterization, but with strong connections to modelling and design. At the scale of 100 qubits, complete characterization of a quantum computer becomes infeasible, so one must be clever about what information to extract and how to do it. The aims of the research project are therefore (i) to develop methods for approximate, selective, and/or partial tomography of quantum states and processes on large quantum computers and (ii) to develop strategies for inferring model parameters, e.g., coupling strengths and noise levels, from measurement data from these devices.
Who we are looking for
The following requirements are mandatory:
• To qualify as a Doctoral student, you must have a Master's degree (masterexamen) of 120 credits or a Master's degree (magisterexamen) of 60 credits* in Physics, Mathematics, Computer Science, or equivalent
• Excellent written and verbal communication skills in English
• Ability to program in high-level languages such as Python or C
• for students with an education earned outside of Sweden, a 4-year Bachelor's degree is accepted.
The following experience will strengthen your application:
• Experience from working on quantum computing
• Experience from working on quantum state, process or measurement tomography, or other methods for characterizing and benchmarking quantum computers or other quantum systems
We value a collaborative attitude and an interest in working both in teams and independently. Self-motivation, attention to detail, and a problem-solving analytical ability are important personal qualities for this position.
What you will do
• Take courses at an advanced level within the Graduate school of Microtechnology and Nanoscience
• Develop your own scientific concepts and communicate the results of your research verbally and in writing
• The position generally also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to 20 percent of working hours
• Develop methods for approximate, selective, and/or partial tomography of quantum states and processes on large quantum computers
• Develop strategies for inferring model parameters, e.g., coupling strengths and noise levels, from measurement data from large quantum computers
• Connect the characterization methods and strategies you develop to theoretical modelling and design work for large quantum computers, and to the experimental work on building large quantum computers
Contract terms
• The Doctoral student positions are fully funded from start.
• The position is a fixed-term appointment of four years, with the possibility to teach up to 20%, which extends the position up to five years.
• A starting salary of 34,550 SEK per month (valid from May 25, 2025).
• Doctoral studies require physical presence throughout the entire study period. A valid residence permit must be presented by the study start date; otherwise the admission may be withdrawn.
What we offer
• As a Doctoral student at Chalmers, you are an employee and enjoy all employee benefits. Read more about working at Chalmers and our benefits for employees.
• A dynamic and inspiring working environment in the coastal city of Gothenburg.
• Read more about Sweden's generous parental leave, subsidized day care, free schools, healthcare etc at Move To Gothenburg.
Chalmers is dedicated to improving gender balance and actively works with equality projects, such as the GENIE Initiative for gender equality and excellence. We celebrate diversity and consider equality and inclusion as fundamental aspects of all our activities.
If Swedish is not your native language, Chalmers offers Swedish courses to help you settle in.
