Postdoc in Single photon quantum technologies

Postdoc position:

The Niels Bohr Institute (NBI) at the University of Copenhagen is seeking an enthusiastic researcher for a postdoc in the quantum photonics group (www.quantum-photonics.dk) on next-generation single-photon quantum devices within the project “FIRE-Q: Field-Ready Single-Photon Quantum Technologies”.

Postdoc in Single photon quantum technologies

The position will be part of the Center for Hybrid Quantum Neworks (Hy-Q, https://hy-q.nbi.ku.dk/) led by Prof. Peter Lodahl. The center is a collaboration between the quantum nanophotonics group and the groups of Prof. Anders Sørensen (www.tqo.dk) and Prof. Albert Schliesser  (https://nbi.ku.dk/english/research/quantum-optics-and-photonics/quantum-optomechanics/).

In total the center employs approximately 50 scientists working on hybrid quantum networks.

About the project:

The successful candidate will be joining the Innovation Fund Denmark’s FIRE-Q project:

  • FIRE-Q is an international project between industry and academia involving three major Danish universities (University of Copenhagen, Technical University of Denmark, and Aarhus University) and four companies in photonic technology.
  • FIRE-Q’s vision is to bring single-photon quantum technology to the market, enabling unbreakable secure communication and ultimately parallel quantum computing
  • The key building block is a source of single photons
  • That can be transmitted over long distances in existing optical fiber networks.
  • Following a modular approach, we will deliver the hardware required for photonic quantum computing in a scalable photonic platform.

At NBI, we have developed a field-ready single-photon source at telecom wavelength using frequency conversion together with industrial and academic partners. As a postdoc you will perform real-world field tests of quantum-secure communication protocols and develop new technology towards the realization of fully device-independent quantum key distribution systems. 

About the candidate:

We are looking for an ambitious and driven researcher with strong applied- and innovation-oriented mindset, with a keen interest in working in applied research. The ideal candidate holds a Ph.D. in physics or optical engineering and has a strong experimental background in the areas of quantum optics, quantum photonics, or semiconductor optics. Experience working with cryogenic equipment, as well as quantum key distribution are a plus.
