PhD fellowships in Quantum Optics and Quantum Sensing Full-time

PhD Fellowship In Quantum Optics And Quantum Sensing

The Niels Bohr Institute invites applicants for PhD fellowships in Quantum Optics and Quantum Sensing. Start date is 1 January 2027 or as soon as possible thereafter.

The projects will contribute to the development of quantum sensors based on room temperature atomic ensembles. Atomic vapours in spin protecting environment have been developed at our laboratory and used as ultrasensitive sensors of electromagnetic fields. Quantum limits of sensitivity set by the interplay between measurement imprecision and measurement quantum backaction have been explored and methods towards overcoming those limits have been developed. The PhD projects will contribute to two main modalities in quantum sensing being developed at our group, magnetometry and magnetic induction tomography. Generation of entangled and squeezed states of collective atomic spin and light for enhanced sensitivity will be explored. Effects of entangled states of light and atomic spins on the limits of sensitivity to electro-magnetic fields will be investigated. Optimized quantum limited sensors will be incorporated in magnetometers optimized for specific tasks. Projects will ultimately aim at applications of entanglement-enabled atomic sensors for bio-medical sensing in collaboration with medical professionals.

The group is a part of the Niels Bohr Institute (Department of Physics), the Faculty of Science, University of Copenhagen. Research will be carried out at QUANTOP laboratories and is part of the Copenhagen Center for Biomedical Quantum Sensing – CBQS. We are a vibrant group of approximately 20 researchers and students working on quantum physics of atoms and light with particular emphasis on interfacing disparate quantum systems with light. Generation of entangled states of light and atoms and their use for quantum sensing, quantum communication and quantum simulations are the core activities at QUANTOP. CBQS is a collaborative effort between the Niels Bohr Institute, Danish Technical University, University of Texas in Austin and medical professionals in Denmark and abroad.

We offer creative and stimulating working conditions in dynamic and international research environment. Our research facilities include modern laboratories located on Blegdamsvej 17, Copenhagen Ø.

Principal supervisor is Prof. Eugene Polzik, Polzik@nbi.ku.dk

To be eligible for the regular PhD programme, you must have completed a degree programme, equivalent to a Danish master's degree (180 ECTS/3 FTE BSc + 120 ECTS/2 FTE MSc) related to the subject area of the project, e.g. [relevant educations]. For information of eligibility of completed programmes, see General assessments for specific countries and Assessment database.
