The members of the project group have actively participated in raising awareness of the importance of quantum technologies among the general public, fellow researchers, and decision makers (e.g. public lecture in the scope of European Quantum Week, Nov 2-6 2020; Radio show Frekvenca X, 3 parts in Jan, Feb 2021; public appeals in mass media such as "Sobotna Priloga”). Some of these activities are documented in bibliographic database COBISS with COBISS IDs: 58047747, 49109251, 50302467, 48191747, 30522663, 31903527, 29533991, 1114509406, 32686119.
D.04 Initiative to set up a new research area in Slovenia
COBISS.SI-ID: 48191235In recent years, it has become possible to control, manipulate and detect individual quantum objects such as photons, ions and atoms with great precision. A new field has emerged where quantum physics and engineering are intertwined. Quantum technologies thus exploit quantum effects such as superposition, entanglement and tunnelling for practical applications such as quantum computers, simulators, sensors and encryption devices. The lecture outlined the basics of some selected quantum technologies, then introduced cold atoms and some key experiments that make cold atoms one of the main players in quantum technologies. The last part of the lecture was devoted to the newly established Cold atom laboratory in Ljubljana, where in 2016 we achieved Bose-Einstein condensation of cesium atoms and created cesium solitons, and to present our activities in the field of quantum sensors.
B.04 Guest lecture
COBISS.SI-ID: 32064807In this invited talk held at the International Communication Seminar of Gunma College, Maebashi, Japan, the basic concepts of quantum technologies were presented. They are all based on our ability to manipulate, control and detect single atoms, ions or photons. The cold atoms are one of the most promising technologies. Few examples were discussed to show how we can use them as quantum simulators, sensors and memories.
B.04 Guest lecture
COBISS.SI-ID: 32486439Optically pumped magnetometers can be adapted for measurements of low frequency or quasi-DC signals to radio-frequency signals used in spectroscopy applications such as NQR and NMR. In comparison to SQUD magnetometers they do not need cryogenic cooling and are thus much easier to maintain.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 18133849In this thesis we describe the use of the Faraday effect for operation of an optical magnetometer with hot cesium vapor, a magnetometer with cold cesium atoms and for non-destructive imaging of cold atoms. In particular, the experiments for characterization of optical pumping, magnetometer sensitivity and Faraday rotation are presented, along with radio-frequency background noise measurements. We also observe the propagation of the cold atom clouds with series of Faraday images and compare destructiveness for different detunings of the imaging beam.
