Postdoctoral Researcher for Anyon Quantum Technologies

Aalto University

Espoo, Finland

An experimental Postdoc position in the field of superconducting quantum correlations in topological materials is available in the NANO group, Department of Applied Physics at Aalto University, Finland. We are leading research in the field of quantum circuits and superconducting hybrid circuits based on novel two- dimensional van der Waals materials. These hybrid-circuits form a promising direction within the emerging field of quantum technologies, which enables a.o. supersensitive sensors for detection flux, charge, and phonons at the sensitivity limits governed by quantum mechanics. This field of research has made tremendous progress in recent years, and presently offers plenty of exciting opportunities for young scientists, in both academia and industry.

This research is motivated by the recent developments in anyon physics. The fractional quantum Hall states provide a unique testbed to probe the exotic quantum statistics of the anyons. We have recently demonstrated the Abelian quantum statistics in an anyon collider geometry fabricated in GaAs/AlGaAs. In this postdoctoral research, we will work towards the development of interferometry for the non-Abelian anyons in the hybrid material platform such as superconductivity proximities graphene-based devices at high magnetic fields, where Landau levels coexist with superconductivity. In such devices, strong electronic interactions may provide novel particles and parafermions. The control manipulation of non-Abelian anyons will set the benchmark for topological quantum computation.

Your role

Being a Postdoc, you will design, fabricate and characterize your own devices using in-house state-of-art micro and nano-fabrication facilities. The electrical measurement will be performed down to 10 mK and in the field as high as 14 T. A low-frequency cross-correlation spectroscopy will be optimized to probe quantum statistics and further extended to develop microwave spectroscopy in the GHz regime.

Your experience and ambitions

We are looking for a bright, motivated researcher to join our team. Prior laboratory experience in the fields of mesoscopic physics, cryogenics, microwave electronics, circuit design, and clean-room techniques, and instrument programming is a plus. We also encourage applications from electrical engineering who have a strong interest in physics and who wish to explore the possibilities of quantum technologies for electrical measurements in general.

We require the candidates to have excellent skills in English. Finnish language is not required. To be eligible, a postdoctoral researcher must hold a PhD degree in a suitable field.
