Postdoc in Experimental cold atomic physics
The Novo Nordisk Foundation Quantum Computing Programme (NQCP) is establishing a talented and diverse international team to create a cutting-edge quantum programme in the heart of Copenhagen, Denmark. At the Niels Bohr Institute, University of Copenhagen, where the formulation of Quantum Mechanics was born 100 years ago, we aim to establish an international quantum computing programme, funded by the Novo Nordisk Foundation, that will drive research and innovations at multiple levels - from developing scalable quantum processor technologies to solutions for the quantum-classical control and readout interface, and all the way to quantum algorithms and applications. The long-term mission of the programme is to develop fault-tolerant quantum computing hardware and quantum algorithms that solve life-science-relevant chemical and biological problems.
NQCP is looking for a highly skilled postdoctoral researcher to join the Neutral Atoms group. The group currently consist of a team of 7 people led by Ass. Prof. Stefan Alaric Schäffer. We use two-electron systems such as Strontium and Ytterbium to develop new methods for atomic interaction, state control and readout that guide the Neutral Atoms pilot line at NQCP.
The project
The candidate will be working on cavity-enhanced interaction and readout methods in ultracold strontium atoms. Cavity-based interaction of many atoms provides a platform for superradiantly enhanced or subradiantly suppressed decays that can generate complex interactions across programmed atomic array. These processes can decohere information storage, enhance readout speeds or protect atomic states from decay, making the method a useful resource for quantum computation infrastructure. The groups newly established laboratory facilities provide state-of-the-art environment for cold-atom experiments, with ultra stable lasers and frequency comb infrastructure.
The successful candidate is likely to have some of the following qualifications
- Proven experimental experience in ultracold atoms.
- Great technical insight and curiosity.
- Experience designing optical, laser and electronic systems.
Why Us?
Joining NQCP now, you will be involved from our early stages and contribute to the fulfilment of the mission of NQCP. We want to make Denmark a world leader in quantum research, and we hope to attract people from all over the world.
Life in Denmark is supported with strong social services (free universal healthcare, free/subsidised language courses, paid parental leave, subsidised day care institutions and excellent public schools). Our work culture is very egalitarian and prioritises work life balance. Dual career families are the norm, and workplaces offer flexibility to support everyone in having both an exciting career and good family time. Danish cities are known for having excellent infrastructure, for example through widespread bike path networks. We can also offer a thriving food-scene, excellent museums, and beautiful natural scenery.
