The renowned journal Physics World announced the 2021 Breakthrough of the Year – and the two winning papers on quantum entanglement of two macroscopic objects are based on work of Professor Eugene Polzik from the Niels Bohr Institute, University of Copenhagen who was the first to use the technique.

2021 Breakthrough of the Year acknowledges Eugene Polzik

 Cell experiment: Quantum teleportation, quantum memory, entanglement and measurements beyond the standard quantum limit with ensembles of room-temperature Cesium atoms.

Quantop research: Cell experiment

 Nanofiber experiment: In the Nanofiber group we use measurements at the quantum level to prepare interesting quantum states in ensembles of laser cooled atoms.

Quantop research: Nanofiber experiment

 Quantop research: We run experiments where quantum light is used to perform tasks in quantum sensing and quantum communication.

 Quantum membranes: We pursue quantum experiments with membranes that are macroscopic and nano-scale at the same time: they are a millimeter across in size, so that the can be discerned with bare eye—but only 100 nm thick, that is just some thousand atom layers.

 About the Quantop research group: QUANTOP offers both specialized courses on the bachelor and master level as well as contributing to the overall teaching and research aims of the NBI. The center is funded by an ERC starting grant and DARPA, and the group is world leading in its research fields of quantum optics, atomic physics and optomechanics.

QUANTOP – Center for Macroscopic Quantum Systems

The Danish Center for Quantum Optics (QUANTOP) started as a DNRF "Center of Excellence" in 2001. QUANTOP’s research is focused on exploring quantum effects at the interface between light and matter.

Research at Quantop
At QUANTOP - the Quantum Optics Center – we study quantum effects at light-matter interface. Particles of light, photons, are great for creating, reading out and transmitting quantum information between material objects.
