Doctoral Student In Quantum Information Theory

KTH Royal Institute of Technology, School of Electrical Engineering and Computer Science

Third-cycle subject: Electrical Engineering

The project is funded by the Swedish Research Council and the Wallenberg Centre for Quantum Technology (WACQT) and addresses fundamental questions in quantum information science, with applications to quantum communication, quantum computation, and other quantum information-processing tasks. Its overarching goal is to determine the ultimate limits on the resources required and the performance in such tasks, while also developing explicit protocols that achieve or approach these limits. A central challenge is to express these limits in mathematically tractable and computationally accessible forms. Ideas and methods from quantum Shannon theory will be especially useful, alongside tools from entanglement theory and the broader mathematical foundations of quantum information. The project will investigate fundamental information-theoretic quantities including entropy, mutual information, channel capacities, and measures of entanglement, and how they behave when quantum systems or information-processing resources are combined. Questions of additivity and nonadditivity constitute an important part of this broader research program.

Supervision: Professor Mikael Skoglund

To be admitted to postgraduate education, the applicant must have basic eligibility in accordance with either of the following:

• passed a second cycle degree (for example a master's degree), or
• completed course requirements of at least 240 higher education credits, of which at least 60 second-cycle higher education credits, or
• acquired, in some other way within or outside the country, substantially equivalent knowledge

The applicant needs to demonstrate excellent background in mathematical skills relevant to information theory, linear algebra and probability theory.

In addition to the above, there is also a mandatory requirement for English equivalent to English B/6.

In order to succeed as a doctoral student at KTH you need to be goal oriented and persevering in your work. During the selection process, candidates will be assessed upon their ability to:

• independently pursue his or her work
• collaborate with others,
• have a professional approach and
• analyze and work with complex issues.

Prior experience in quantum information theory is a plus.

After the qualification requirements, great emphasis will be placed on personal skills.

Target degree: Doctoral degree
