丹麦技术大学量子光学博士后职位

DTU Fotonik works with all areas of photonic engineering, including a strong focus Ｏn optical communications.

We are now seeking a Postdoc in optical quantum communication systems.

Responsibilities and tasks
The focus of the position will be single-photon sources and quantum key distribution (QKD) signals, i.e., an optical quantum key used to secure and encrypt data. A key issue for the postdoc is to demonstrate QKD schemes as well as Ｏn-demand single-photon sources that operate preferably without elaborate set-ups like cryogenics or electro-magnetic laser-cooled atom-traps. Furthermore, it is desirable if the wavelength of operation is in the telecom window i.e. around 1550 nm.

Regarding the QKD schemes, the postdoc will explore novel QKD schemes using advanced fibres that support propagation of so-called higher order modes, and pursue the integration of single-photon sources with integrated higher order mode couplers. Ｏne goal for the postdoc will be to conduct experiments of QKD transmission over fibre at 1550 nm, including QKD Ｏn higher order modes.

Another goal is to explore methods to create efficient Ｏn-demand single-photon sources based Ｏn integrated nonlinear silicon waveguides, and in addition create a platform for quantum interference experimental investigations.

The postdoc will focus Ｏn developing experimental frameworks for demonstration of QKD and single photon generation. However, appropriate theoretical and numerical work should support the effort.

The postdoc may benefit from international collaboration with partners at Applied Communication Sciences (ACS), New Jersey, USA, Universities of Sydney and Bristol, who are world leading in this field. The postdoc project will be part of the newly started Research Centre of Excellence, SPOC (Silicon Photonics for Optical Communications) and will work in close collaboration with many other activities within the centre.

Apart from the research outlined above the postdoc position will involve a limited amount of teaching mainly in the form of supervising student projects.

Qualifications
Candidates should have a PhD degree or equivalent within experimental quantum optics.

A strong background in quantum communications and quantum signal processing is preferred. Experience with nonlinear optics, silicon photonics and fiber optics is also of high importance.

We offer
We offer an interesting and challenging job in an international environment focusing Ｏn education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world.

Salary and terms of employment
The appointment will be based Ｏn the collective agreement with the Confederation of Professional Associations. The allowance will be agreed with the relevant union.

The period of employment is 2 years.

Place of work is DTU Lyngby Campus.
