Fedor Jelezko

L2Fedor Jelezko – director of the Institute of Quantum Optics and fellow of the Center for Integrated Quantum Science and Technology (IQST) at Ulm University. He studied in Minsk (Belarus) and received his Ph.D. in 1998. After finishing the habilitation in 2010 at Stuttgart University he was appointed as a professor of experimental physics in Ulm in 2011. For his scientific achievements in the field of solid state quantum physics, he has received several honors, in particular, the Walter Schottky Prize of the German Physical Society, ZEISS Research Award and in 2018 he received the first Shpol’skii-Rebane-Personov medal and prize.

Professor Jelezko has more than 170 papers in refereed international journals including 5 articles in Science, 2 articles in Nature, 18 articles in the Nature family of journals (Nature Materials, Nature Physics, Nature Nanotechnology, Nature Photonics, Nature Communications). This work has achieved more than 10 000 citations and an H-Index of 49. Jelezko listed among most cited researchers in Thomson-Reuters list (2014 and 2015).

His research interests are at the intersection of fundamental quantum physics and application of quantum technologies for information processing, communication, sensing, and imaging. Professor Jelezko makes the control of single atomic scale systems in solid state environments possible. Coherent control techniques similar to nuclear magnetic resonance are combined with ultrasensitive optical detection of single atoms. The focus of his pioneering work is on extremely pure, artificially produced diamonds. Jelezko’s research is essential for highly precise sensors and new imaging-technologies.

Diamond is not only the king gemstone, but also a promising material in modern technology. Less known is that defects in diamond can be used for quantum information processing. Owing to their remarkable stability, colour centers in diamond have already found an application in quantum cryptography. Furthermore, it was shown that spin states associated with single nitrogen-vacancy defects can be detected optically. Single spins in diamond belong to most promising solid state qubits. The long living spin state of single defects can be readout optically and manipulated using well established magnetic resonance technique. Furthermore, excellent coherence properties of single spins associated with defects in diamond are preserved even at room temperature. Jelezko is aiming to develop scalable quantum register based on single nuclear and electron spins. The small scale quantum register consisting of single electron and nuclear spins can be used in experiments aiming to test fundamental questions of quantum mechanics in solid state. One of the crucial advantages of defects in diamond is intrinsic coupling of spins to photons allowing their use in quantum communication protocols.
