The Department of Physics is one of the biggest departments within the Faculty of Science and supports a broad range of basic research in experimental and theoretical physics. It has about 250 employees of which 95 are PhD students. Many have been internationally recruited. The Department is part of the AlbaNova University Center, which apart from the Department of Physics houses the Department of Astronomy, the Physics Departments at the Royal Institute of Technology (KTH), and the Nordic Institute for Theoretical Physics (Nordita). 

The Department of Physics and Stockholm University is affiliated to Stockholm Dual Career Network (SDCN) that supports expat partners with professional events, career-related advice and by building a social network in their new hometown,

Project description
The interdisciplinary field of quantum information processing and communication connects quantum mechanics/optics/electronics with classical information theory to achieve tasks in information and communication that are impossible with classical methods. This fusion has led to new concepts such as the qubit, quantum teleportation, quantum cryptography, and quantum computing.

Quantum information has also revitalized the discussions about the foundations of quantum theory. The field is currently very active and is driving for progress in both physics and computer science, information technology. The research objectives of our group include experimental preparation and characterization of multipartite entanglement and tests on the foundations of quantum mechanics, such as the locality and the contextually.

In quantum communication, the objectives are the implementations of quantum key distribution, quantum random number generation, secure quantum multiparty communication, and qubit and entanglement assisted communication protocols.

The aim of this project is to develop security tools for quantum cryptography protocols and communication system solutions. The practical security of quantum systems verification will be guaranteed by successive iterations of security loophole demonstrations and countermeasure implementations.

This project is part of the Wallenberg Centre for Quantum Technology (WACQT), a 12-year, billion-SEK initiative started in 2018 with the purpose of advancing Swedish academia and industry to the forefront of quantum technology.

Main responsibilities
The postdoc will be working with programming, data analysis, benchmarking, and modelling, as well as application of the developed methods to secure quantum communication project.

Qualification requirements
Postdoctoral positions are appointed primarily for purposes of research. Applicants are expected to hold a Swedish doctoral degree or an equivalent degree from another country.

Assessment criteria
The degree should have been completed no more than three years before the deadline for applications. An older degree may be acceptable under special circumstances, which may involve sick leave, parental leave, clinical attachment, elected positions in trade unions, or similar.

The successful candidate should be highly motivated and should have a Ph.D. in physics and computer science or related field, and a strong background in cryptography and IT security. Experience with quantum communication is important. Excellent skills in computer programming (primarily C++, Python), computer networks, and knowledge of IT security tools are necessary merits.

We value a collaborative attitude and an interest in working both independently and togheter in a team, sharing best practices and assuming responsibility. Self-motivation, attention to detail, and a problem-solving analytical ability are important personal qualities for this position.

Terms of employment
The position involves full-time employment for a maximum of two years, with the possibility of extension under special circumstances. Start date as per agreement.

Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
