Stefano Paesani

PhD opportunity in photonic quantum error correction at the Niels Bohr Institute, University of Copenhagen. The project sits within the Novo Nordisk Foundation Quantum Computing Programme (NQCP), an international quantum computing initiative in Copenhagen that works on scalable quantum processor technologies, quantum algorithms and applications, with a long-term goal of fault-tolerant hardware and algorithms for life-science-relevant problems. This PhD focuses on fault-tolerant photonic quantum computing with qudits and group surface codes . You will develop theoretical models and software to study how photonic error-correcting codes can be implemented in photonic circuits, then use numerical simulations to evaluate how well they protect information, how reliably they support computation, and what resources they require. The research is centred on theory, programming and simulation, while maintaining a close connection to photonic hardware. The work is embedded in the photonics research environment at the Niels Bohr Institute and connected to a wider, dynamic quantum programme hosted by NQCP. You will collaborate with researchers working on quantum computing architectures, quantum error correction and photonic quantum technologies, and the project includes collaboration between the University of Copenhagen and the University of Southern Denmark. The principal supervisor is Associate Professor Stefano Paesani at the Niels Bohr Institute. The co-supervisor is Professor Apoorv Tiwari at the University of Southern Denmark. The post is part of an ambitious research environment aimed at strengthening Denmark’s role in quantum research and building a career path in advanced quantum computing. The programme offers two possible routes depending on prior education: a regular PhD route or an integrated MSc and PhD route. The project is supported by the Danish e-Infrastructure Consortium (DeiC).
