The Department of Physics is currently seeking to recruit candidates to the position of


The position starts earliest on November 1, 2021 or as agreed, for a fixed-term of 2 years.

The Hybrid Quantum Technologies group at University of Jyväskylä (Finland) seeks a talented postdoctoral researcher in the field of optomechanics and/or low temperature physics to join the group. AMO or other quantum information background can also be suitable.

The project

The postdoctoral researcher will work in a project where the goal is to achieve quantum level control of silicon optomechanical systems at millikelvin temperatures with feedback methods. This will then be used in a larger system combining the optomechanical structure with qubits. The motivation is both in probing the quantum control and coherence limits of mesoscopic mechanical systems and in advancing silicon quantum technologies. The project will give an excellent background for an academic or industrial career related to quantum technologies.

The group

We study the quantum potential of silicon technologies, concentrating especially on optical interfaces for silicon spin qubits and optomechanical systems. The motivation comes from both in enabling practical quantum sensors and quantum computing components and in studying fundamental physics in these on-chip quantum physics testbeds. Fundamental questions that we aim to investigate include the ultimate quantum coherence limits and possibilities for superposition states in macroscopic systems. Our experimental toolset includes optical and electrical (both DC and microwave) measurements at low temperatures (3 K and mK) as well as advanced nanofabrication.

The group was formed in the fall of 2018 and we are a smallish group that is still growing. You would be working closely together with the whole group but especially with a PhD student assigned on the same project. Our webpage:


In the project, you will need to combine advanced optical and microwave methods at low temperatures, strong theoretical understanding of the physics involved, and skills in numerical modelling (Python or Matlab preferred). Preferably, you would already master some of these, but rest can be learned during the project. You will guide PhD and MSc students and can drive the project forward.

You need to have a doctoral degree (or be close to getting one) in physics or related engineering sciences and must have research experience in an international environment. We seek an excellent candidate with relevant experience, preferably in quantum optics, nanophotonics, low temperature physics or other AMO physics.

The duties, qualification requirements and language skills of a Postdoctoral Researcher are stipulated by the University of Jyväskylä Regulations and language skills guidelines. A good command of English is required and a proficiency to teach in English will be considered beneficial. The PhD degree required for the position must have been completed before starting the position.
