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 postdoc to help scale up our efforts to build a quantum computer by developing and implementing models for, and ways to characterize the workings of, the quantum computer and its constituent parts.
Project description
Modelling a quantum computer on a classical computer is an inherently hard problem, since the number of states that one needs to keep track of grows exponentially with the number of qubits. Adding noise from a surrounding environment increases the degrees of freedom even further. Similarly, to characterize the state of such a quantum system, or the processes that take place during the operation of the quantum computer, will in general require exponentially many measurements to be performed on the system.
The succesful candidate will develop models that strike a balance between being able to incorporate many qubits and being able to describe the noise affecting these qubits with sufficient detail. The candidate will also develop and refine protocols to efficiently characterize the states and processes in the quantum computer by extracting the most relevant information about them. The work will be done in close collaboration with the experimental team, and will also inform theoretical research on quantum algorithms carried out in our centre.
This project is part of the Wallenberg Centre for Quantum Technology (WACQT), a 12-year, 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.
Information about the division and the department
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). 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 80 members (faculty, permanent research staff, postdoctoral researchers, PhD students, and undergraduate students) and is expanding. WACQT is committed to promoting career development, diversity, and gender equality through networking and supporting activities.
Our department (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
Your major responsibility as a postdoc is to develop and implement ways to model and characterize quantum computers that are being scaled up to tens and hundreds of qubits. This will include both analytical and numerical work, and also collaboration with experimentalists who develop, build, and run the quantum computers at Chalmers. You may also help in supervising PhD or master students working on modelling and characterization of quantum computers
Qualifications
Required qualifications:
• PhD in Physics or neighbouring fields
• 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
• Experience from programming in collaborative projects
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.
To qualify for the position of postdoc, you must hold a doctoral degree awarded no more than three years prior to the application deadline (according to the current agreement with the Swedish Agency for Government Employers).
Contract terms
This postdoc position is a full-time temporary employment for two years, with a possibility of extension by another year.
