PhD Student in Quantum Information Theory & Experiment Interdisciplinary Transformation University (IT:U) in Austria

Interdisciplinary Transformation University (IT:U), Austria’s first public interdisciplinary university dedicated to digital transformation, invites applications for three PhD positions in Quantum Information Theory & Experiment. The IT:U Doctoral School PhD Program COMPUTATIONAL X offers a unique opportunity to join a vibrant, international research environment in Linz, Austria, starting October 2026. The program is led by Professor Beatrix Hiesmayr, a principal investigator with extensive experience in academia across multiple countries.

The research focus is on next-generation quantum computers, which must handle tens to hundreds of qubits/qudits, entering regimes where current certification methods for multipartite, high-dimensional quantum resources are insufficient. Key challenges include developing scalable benchmarks and theoretical figures of merit for large, high-dimensional systems, maintaining stable calibrations during extensive data acquisition, and harnessing these systems for practical applications such as quantum key distribution and human imaging with high-energy photons.

The interdisciplinary team at IT:U spans experimental and theoretical quantum physics, medical applications, and computing. Available projects include:

• Theoretical quantum information: Develop and analyze theoretical quantities characterizing quantum properties (e.g., entanglement), emphasizing experimental implementability and validation.
• High-energy photons for applications: Extract information from experiments and explore how these insights can be leveraged for medical applications.
• Orbital angular momentum (OAM) entangled multipartite photons: Conduct experimental research involving OAM-entangled states, including hands-on laboratory work.

PhD students will conduct research, write and publish scientific papers, attend conferences, collaborate with other research groups, contribute to academic teaching (up to 2 weekly credit hours), support third-party funding applications, and comply with academic standards and ethical guidelines. The program structure includes focused group work, research lab modules, and Project Integrated Courses (PICS) in the first year, followed by thesis development, interdisciplinary seminars, and project assistant work over the next three years. The program concludes with thesis submission and defense after four years.

Applicants must hold a degree equivalent to a master's in physics, mathematics, computer science, or related fields. Required skills include basics in quantum physics, programming, computational modeling, independent and team work, and strong English communication (CEFR C1 or equivalent). Motivation for teaching and outreach projects is desirable.

IT:U offers innovative working conditions, an office kitchen with complimentary supplies, and the Austrian KlimaTicket OÖ for unlimited public transport within Upper Austria. The gross salary is EUR 2,832.10 per month (30h/week), with optional supplementary contracts for teaching or research up to 10 hours. International mobility and exchange are encouraged, with opportunities for short stays at collaborating institutions in Europe, North America, and Asia.

To apply, submit your application via the online form, including your CV, diplomas, transcripts, motivational letter (max. 2 pages), and up to three contacts for recommendations. The positions remain open until filled, with a final deadline of 30 April 2026. Early applications are encouraged as review is rolling. IT:U values diversity and welcomes applicants from all backgrounds.
