Application deadline: Monday, June 29, 2026Research group: Centre for Quantum Technologies Theory GroupEmployer web page: https://majulab.cnrs.fr/Job type: PostDocTags: quantum energeticsquantum opticsquantum thermodynamicsA Research Fellow position is open in the group of Alexia Auffèves (CNRS-MajuLab,CQT, Singapore) to work on fundamental aspects of quantum energetics applied to quantum optics. The candidate will explore relations between energy and non-classicality, both to provide new ways to characterize non-classical quantum states of light, and optimize processes to produce them. Context and goal of the project. Non-classical quantum states, from non-Gaussian states of light like Schrödinger cat states to entangled states, are precious resources for quantum technologies. Beyond their potential practical use, they also provide appealing fundamental objects to explore the quantum world. The focus of the project is on identifying and understanding energetic imprints of non-classicality (entanglement, non-Gaussianity, squeezing...). Such a fundamental understanding unlocks multiple research paths, from the definition of new measures and witnesses of non-classicality, to the construction of optimal processes under energetic constraints, or the identification of energetic advantages of quantum nature. Role of the research fellow. The fellow will contribute to build new concepts and thought experiments, develop related analytical and numerical tools, conduct feasibility studies and elaborate realistic proposals and will contribute to the data analysis of the experiments possibly inspired by the theoretical work. They will supervise PhD and master students, write papers, present the work in conferences and actively contribute to the scientific life of the group. The project has a broad goal and creativity is encouraged. About the funding origin. The project is partially funded through the French Quantum Strategy (funding initiatives OQuLus and NISQ2LSQ), which aim to build photonic and superconducting quantum computers. The work will involve collaborations with leading French academic groups and startups and regular trips to France to sustain these collaborations. About the hosting group. The group has pioneered the research at the boundary between quantum optics and quantum energetics/thermodynamics, exploiting the richness of quantum optics to explore energetics in the quantum realm, and building new energetic figures of merit to witness quantum effects or assess the cost of quantum resources. Larger working environment. The group is part of MajuLab, a joint international lab whose signatory institutions are the French Centre National de la Recherche Scientifique (CNRS), the Universite Côte d'Azur (UCA), Sorbonne Université (SU), the National University of Singapore (NUS) and the Nanyang Technological University (NTU). It is physically based inside the Centre for Quantum Technologies, which offers a highly stimulating environment for quantum foundations and quantum technologies and the potential for many discussions and collaborations. Qualifications – PhD in theoretical quantum physics and open quantum systems, with a focus on realistic models. Experience in quantum control and/or non-Gaussianity/non-classicality of CV systems and/or quantum trajectories will be a very strong plus. – Excellent analytical, organizational, and communication skills. – Capacity to work in multidisciplinary teams and at multiple levels of description. – Proven track record of published research and presentations in relevant fields. – Creativity, autonomy and ability to think out of the box.
What We Offer – Opportunity to play an instrumental role in the emerging field of fundamental quantum energetics. – Potentially long-term research fellow position, giving ample time to develop new skills and reach ambitious challenges. – Opportunity to supervise PhD students and interns, freedom to define and execute workplans. – Various collaborations in France and Singapore within highly stimulating environments. – Excellent networking opportunities with leading experts from academia and industry. – Excellent working conditions: competitive salary + benefits: up to 110000$/year after taxes (housing allowance included), plus medical plan and relocation subsidy. How to Apply Interested candidates should submit their application by sending an email to alexia.auffeves@cnrs.fr including a detailed CV, a cover letter explaining their interest and fit for the role, two or three reference letters, and a list of publications.
