Such computationally hard problems are found, e.g., in optimization, quantum chemistry, materials science, machine learning, etc. Having contributed to starting the research field of superconducting quantum circuits, we are now seeking a PhD student to help in our efforts to build a quantum computer by modelling, analyzing, and improving the design of our quantum processor as we scale it up.
The successful candidate will use theoretical tools to explore how unwanted couplings and crosstalk between qubits in a large processor can be minimized, and fidelities of operations on the processor can be maximized. Achieving these goals will require a judicious choice of both quantum gates to implement and of layout for the processor in terms of qubit frequencies, couplings strengths, and connections.
Information about the project and department
This project is part of the Wallenberg Centre for Quantum Technology (WACQT), a 12-year, 1.5-billion-SEK initiative started in 2018 with the purpose of advancing Swedish academia and industry to the forefront of quantum technology, and to build a Swedish quantum computer. Our team is also a prominent partner in the internationally competitive OpenSuperQPlus collaborative project working to build a quantum computer within the EU Flagship on Quantum Technology.
Building a quantum computer requires a multi-disciplinary effort involving experimental and theoretical physicists, electrical and microwave engineers, computer scientists, software engineers, and researchers in materials science and nanotechnology. We are developing the superconducting quantum devices, control circuits, firmware, and methods required to make the quantum computer a reality. This development takes place is in a close, fruitful collaboration between experimentalists in the Quantum Technology Laboratory (QTL) and theorists at the Applied Quantum Physics Laboratory (AQPL) and the Department for Computer Science and Engineering. In this collaboration, the main tasks of the theorists are to help model the hardware and to develop application use cases for the quantum processor.
Our WACQT team at Chalmers currently has about 100 members (faculty, permanent research staff, postdoctoral researchers, PhD students, and undergraduate students). WACQT is committed to promoting career development, diversity, and gender equality through networking and supporting activities.
Our department, Department of Microtechnology and Nanoscience (MC2), is host to the state-of-the-art MC2 Nanotechnology Laboratory cleanroom, the largest such facility in Northern Europe, and our measurement lab at QTL is well equipped with cryogenic and microwave electronic equipment. We are in a position to build and operate large-scale quantum processors!
Major responsibilities
The main responsibilities of a PhD student at Chalmers consist in pursuing doctoral studies by conducting research within your project, in collaboration and independently, leading to results that you will publish in journals and present at meeting and conferences. The work in this project involves theoretical and numerical modelling of the superconducting quantum processor at the physical level.
Your studies also include coursework in your field and common core courses on generic and transferable skills. The position generally also includes teaching on the undergraduate level or other duties corresponding to up to 20 per cent of working hours.
Qualifications
Required qualifications:
• MSc corresponding to at least 240 higher education credits in Physics, or equivalent
• Excellent communication skills in written and spoken English
• Ability to program in high-level languages such as Python or C
Desired qualifications:
• Experience from working on quantum computing
• Experience from working on superconducting qubits
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.
Contract terms
Full-time temporary employment. The position is limited to a maximum of five years.
