Postdoctoral position in propagating photons and their interaction with qubits

The Department of Microtechnology and Nanoscience focuses on research, innovation and education within the fields of future electronics, photonics, and bio- and nanosystems. Close collaborations with Swedish and international partners within academy, industry, and society enables scientific excellence and creates an innovative environment. In addition to the 200 researchers and PhD students, MC2 houses a cleanroom for micro- and nanofabrication with the latest equipment.

Information about the research
The research at the Quantum Device Physics Laboratory (QDP) extends over a variety of different topics. QDP is therefore divided into three subgroups: Experimental Mesoscopic Physics (EMP), Quantum Devices & Oxide Electronics (QuOx) and the Bolometer Group. The focus of the EMP group, where this position will be placed, is quantum information, quantum optics on-chip, molecular electronics, and single electronics.

The research project
For several years, we have pursued research on the quantum properties of propagating microwave photons. In particular, we have studied the interaction between superconducting qubits and microwave photons in open transmission lines.
In this new project we intend to investigate how entangled photons are generated by the Dynamical Casimir effect and how those can can be used to entangle qubits.

We are now looking for a post-doc to continue this research. The work is experimental and involves nanofabrication of superconducting circuits and measurements a milli-kelvin temperatures.

Your major responsibility as a postdoc is to perform your own research in a research group. The position may also include supervising master's and/or PhD students to a certain extent. Another important aspect involves collaboration within academia and with society at large. The position is a stepping stone for future research duties within academia as well as in industry or the public sector.
Position summary Full-time temporary employment. The position is limited to a maximum of two years (1+1).

To qualify for the postdoc position, you must have a doctoral degree in physics; the degree should generally not be older than three years. You are expected to be somewhat accustomed to teaching, and to demonstrate good potential within research. Experience in nanofabrication, cryogenics, and microwave measurements are desired.

The position requires sound verbal and written communication skills in English.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
