About the Institute

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as in architecture, industrial management, urban planning, history and philosophy.

The workplace

The School of Engineering Sciences carries out a wide range of research at the international front line, from fundamental disciplines such as Physics and Mathematics, to Engineering Mechanics with applications such as Aeronautics and Vehicle Engineering. We also offer university degree programs in Engineering Physics, Vehicle Engineering, and 'Open entrance', as well as a number of international masters programmes.

Laser Physics group which is a part of the Department of Applied Physics is engaged in research on novel laser concepts and nonlinear materials, optical material engineering, optical frequency conversion using custom-designed nonlinear photonic structures and low-dimensional optoelectronic media. The Laser Physics group is located at AlbaNova campus in central Stockholm. Co-location with the quantum optics and spectroscopy groups from Stockholm University at AlbaNova resulted in very fruitful collaborative environment. The Laser Physics group is well established internationally and has many collaboration activities around the world. It is our conviction that the research which we pursue should lead to technologies beneficial for rapidly-expanding range and sophistication of photonics applications. The work environment in the group is very international, informal and dynamic.


Good knowledge of nonlinear optics, quantum interference, multifold photon counting, computer control system and data analysis. Experience in working with laser systems, including ultrashort-pulse lasers is a big plus. Experience in design and fabrication of photonic waveguides and resonant photonic structures is a big advantage. The candidate must be strongly motivated to overcome challenges, be able to formulate goals and fulfill them independently. The nature of the project requires good communication skills and collaboration abilities.

Project description

The experimental generation, preparation, manipulation, and detection of the entangled quantum states are of great importance in quantum information protocols. The generation of entangled photons at a well-defined timing and wavelength are crucial for practical implementation of these protocols. Recently, a new type of nonlinear waveguide structures have shown high production rate of photon pair using few mW. The aim of the project is the design, development, and testing of multiphoton entanglement sources. Such sources will consist of cascaded sources of entangled photon pairs and quantum interference. The increasing efficiency, coupling, and long-term stability of these sources are crucial for test of foundations of quantum theory and quantum communications. The project is part of a larger collaboration on secure quantum communications and will involve extensive collaboration with groups working on quantum measurements, single-photon detectors, and quantum memories.
