PhD student position in quantum optics with giant atoms

QUANTUM OPTICS WITH GIANT ATOMS

Information about the research and the Applied Quantum Physics Laboratory
This PhD position will explore the theory for quantum optics with giant atoms. In quantum optics, it is common to assume that atoms can be approximated as point-like compared to the wavelength of the light they interact with. However, recent advances in experiments (at Chalmers, MIT, and other places) with artificial atoms built from superconducting circuits have shown that this assumption can be violated. Instead, these artificial atoms can couple to an electromagnetic field at multiple points, which are spaced wavelength distances apart. Such systems are called giant atoms. The main novelty of giant atoms is that the multiple coupling points give rise to interference effects that are not present in quantum optics with ordinary, small atoms.

The study of giant atoms is still in its infancy. There are many phenomena in quantum optics that need to be revisited for giant atoms, to see whether the added interference effects give rise to new physics. The goal of the PhD project is to find one or more such areas where giant atoms make a difference. Thanks to our collaborations with experimentalists at Chalmers and MIT, there will be excellent opportunities have interesting findings tested in experiment.

At the Applied Quantum Physics Laboratory (AQP lab), we work on theoretical aspects of future high-performance nano-electronic systems. Our research covers a broad spectrum, from fundamental problems to very applied ones. We work in close collaboration with the experimental groups, especially within the Wallenberg Centre for Quantum Technology (WACQT), which is a 10-year, 1-billion SEK effort to advance quantum technology in Sweden and build a quantum computer at Chalmers. Our major research interests cover quantum information processing with superconducting electronics, mesoscopic superconductivity and transport in nanostructures, molecular electronics, and graphene electronics.

Major responsibilities
The main responsibilities of a PhD student at Chalmers consist in pursuing doctoral studies by conducting research within your project, in collaboration and independently, leading to results that you will publish in journals and present at meetings and conferences. Your studies also include coursework in your field and common core courses on generic and transferable skills. The position generally also includes teaching on the undergraduate level or other duties corresponding to up to 20 per cent of working hours.

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

Qualifications
Required:
*MSc in Physics, or equivalent
*Excellent communication skills in written and spoken English
