Experimental PhD in quantum information processing with bosonic modes

We are looking for a highly motivated PhD student to contribute to our ongoing research efforts in experimental quantum information science using superconducting circuits.

Information about the division and the project
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 10-year initiative, started in 2018, for the purpose of advancing 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 (VR), the European Research Council (ERC), and the European Innovation Council (EIC).

In the last 15 years, superconducting circuits based on Josephson junctions have emerged as a leading architecture 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. A quantum bit of information is customarily represented using a pair of energy levels acting as a quantum two-level system. As an alternative strategy, one can encode the quantum bits in nonclassical states of harmonic oscillators (“bosonic modes”), while still relying on the Josephson non-linearity for state manipulation and readout. This latter approach presents advantages such as longer coherence times, resource-efficient quantum error correction, and well-understood loss channels, and is the one that the successful candidate will investigate in this PhD position.

Major responsibilities
You will perform experimental research, both individually and as part of our team, in the field of quantum information processing with superconducting circuits. 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.

Qualifications
To qualify as a PhD student, you must have a master's level 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.
