Quantum electrodynamics with 1D arti cial atoms: from Purcell enhancement to single-photon nonlinearities Supervisor: Prof. Peter Lodahl

Jan W. Thomsen receives annual teaching award at NBI

“For more than five years, Jan Thomsen has captivated class after class as he takes students on a journey into the world of optics,” reads the justification from the students for recommending Jan Thomsen for the Niels…

New superconducting hybrid crystals developed at the University of Copenhagen

A new type of ‘nanowire’ crystals that fuses semiconducting and metallic materials on the atomic scale could lay the foundation for future semiconducting electronics. Researchers at the University of Copenhagen are…

Atoms queue up for quantum computer networks

In order to develop future quantum computer networks, it is necessary to hold a known number of atoms. To do this, researchers from NBI have developed a method with a trap that captures the atoms along an ultra thin…
