PhD positions in quantum information processing and quantum

We are looking for two highly motivated PhD students to contribute to our ongoing research efforts in experimental quantum information science and quantum thermodynamics using superconducting circuits.

Information about the division and the department
At the Quantum Technology division of the Microtechnology and Nanoscience (MC-2) department, we pursue state-of-the art research in quantum information science, microwave quantum optics, and mechanical quantum devices. We are also part of the Wallenberg Centre for Quantum Technology (WACQT), a 12-year initiative to advance Swedish academia and industry to the forefront of quantum technology, and to build a Swedish quantum computer.

In our research group, the 202Q-lab, we use superconducting circuits to explore fundamental and applied questions in the areas of quantum information processing, microwave quantum optics and communication, and quantum thermodynamics. Our research is funded by WACQT, the Swedish Research Council, the European Research Council (ERC), and the European Innovation Council (EIC).

Project description
In the last 15 years, superconducting circuits based on Josephson junctions have emerged as a leading platform to build a quantum computer. Josephson junctions provide a strong and lossless non-linearity that can be used to engineer quantum circuits with tailored energy spectra. In one project, the successful candidate will encode quantum information in nonclassical states of harmonic oscillators, while still relying on the Josephson non-linearity for state manipulation, entanglement, and readout. Using this approach, the candidate will realize a system of multiple harmonic oscillators and run proof-of-principle quantum algorithms on it. Examples include, but are not limited to, quantum error correction and variations of boson sampling. In the other project, the successful candidate will use superconducting circuits to build a range of one-of-a-kind quantum thermal machines. This project addresses two research questions: (i) if and how genuinely quantum effects can provide advantages in thermodynamic processes, and (ii) if quantum thermodynamic effects can be exploited as an enabling technology for quantum information science.

Major responsibilities
You will perform experimental research, both individually and as part of our team, in the field of circuit quantum electrodynamics. You will fabricate state-of-the-art quantum devices and perform microwave measurements with nearly quantum-limited noise performance, taking advantage of the extensive infrastructure and expertise available in our team and division. Your research will benefit from regular interactions with our theory collaborators based in neighboring divisions as well as in other institutions in Sweden and abroad. You will publish your research in established journals and present it at international workshops and conferences.

The position generally also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to 20 per cent of working hours.

Qualifications
You hold a MSc degree in Physics, Engineering Physics, or Applied Physics, or you plan to defend your MSc thesis before July 30, 2022. You have a strong interest in at least two of the following: experimental realizations of quantum processors, quantum information science, quantum optics, microwave engineering, nanofabrication. You see yourself as pursuing a career in research & development or education, either in the academia, or in the industry. You are driven by scientific curiosity and by a desire to make a difference. You can confidently read, write, and discuss science in English. We will consider outstanding candidates with proven track record in any field of physics. Previous experience in experimental condensed-matter physics, atomic, molecular, and optical (AMO) physics, and quantum optics will be regarded as an asset. A theory background in quantum optics and modeling of Josephson circuits will also be appreciated.

Contract terms
Full-time temporary employment. The position is limited to a maximum of five years.
