Doctoral Student in Quantum Information Theory at KTH Royal Institute of Technology, Stockholm

Job Description

KTH Royal Institute of Technology is recruiting a doctoral student in quantum information theory to work out the ultimate limits on resources and performance in quantum communication and computation, and to design protocols that reach them. The project is funded by the Swedish Research Council and the Wallenberg Centre for Quantum Technology (WACQT).

At a glance

• Position: Doctoral student (1 post), School of Electrical Engineering and Computer Science
• Subject: Electrical Engineering (third-cycle subject)
• Supervisor and contact: Professor Mikael Skoglund, skoglund@kth.se
• Funding: Swedish Research Council and WACQT
• Reference: PA-2026-2852
• Apply: 24 September 2026, midnight CET/CEST

About the doctoral project

• Study fundamental information-theoretic quantities, including entropy, mutual information, channel capacities and entanglement measures
• Investigate how these quantities behave when quantum systems or resources are combined, including questions of additivity and non-additivity
• Express performance limits in mathematically tractable and computationally accessible forms
• Develop explicit protocols that achieve or approach those limits, using quantum Shannon theory and entanglement theory

Swedish doctoral positions are salaried jobs rather than scholarships: you are employed by the university, take doctoral courses, do research with a supervisor, and may teach up to a fifth of the time.

What KTH is looking for

• Basic eligibility for doctoral studies: a second-cycle (master’s) degree, or at least 240 higher education credits including 60 at second-cycle level, or equivalent knowledge
• English equivalent to English B/6 (mandatory)
• An excellent background in the mathematics relevant to information theory, linear algebra and probability theory

Nice to have

• Prior experience in quantum information theory

Pay and location

Monthly salary under KTH’s doctoral student salary agreement; the posting gives no figure. Employment is renewed in steps (first up to one year, then up to two years at a time) for a total of up to four years of full-time doctoral education. The position is in Stockholm, Sweden.

How to apply

Apply through the official KTH page. The closing date is 24 September 2026, midnight CET/CEST. Apply for the position and admission through KTH’s recruitment system using the link on the official posting. The application must include copies of diplomas and grades and proof of meeting the English requirement (copies of originals must be certified, with translations into English or Swedish where needed), a CV, an application letter of at most two pages on why you want to do research and how it relates to your studies and goals, and representative publications or technical reports (for long documents, an abstract plus a web link). Applications must arrive by midnight CET/CEST on the closing date.
