IQST Day October 11th, 2017

Location: Ulm University | Albert-Einstein-Allee 11 | O25 H4/5

We have invited two very well renowned keynote speakers who will present their research:

  • Nadav Katz, Hebrew University: Wiring up superconducting devices: Hybrids and meta materials
  • Svenja Knappe, QuSpin Inc. and the University of Colorado, Boulder: Imaging arrays with microfabricated optically-pumped magnetometers


Quantum Metrology, Atomic Sensing and Novel Imaging

8.8.2017: Different roads have been taken towards single spin detection. Most prominent are atomic force microscopy and scanning tunneling microscopy that were able to achieve single electron spin detection over past decade, however conditions were limited to cryogenic temperatures. Our institute in close cooperation with several world leading groups in biology, physics and material science develop the novel approach to image single electron and nuclear spins under ambient conditions. The probe system is an ultrasensitive atomic magnetometer based on single electron spins associated Nitrogen-Vacancy (NV) color centers in diamond. ...more

IQST Symposium "Milestones in Quantum Optics"

4. - 6.7.2017: On the occasion of Wolfgang Schleich's 60th birthday, the center for IQST is organizing the symposium "Milestones in Quantum Optics" in his honor. Many of Wolfgang's friends and colleagues who he has worked with over his illustrious career will be attending. ...more ...more

Research in Biophysics: Transcription

28.04.2017: Transcription is the first step in gene expression, where DNA is transcribed into mRNA. We investigate this complex structural and mechanistic process in the eukaryotic and archaeal system. Thereby, we focus on the main enzyme involved in this event, the RNA polymerase (RNAP), and its several transciption factors to gain structural, dynamic and kinetic information by using single-molecule fluorescence microscopy, fluorescence correlation spectroscopy and optical tweezers ...more

Bose-Einstein condensates in microgravity

25.04.2017: The study of atomic systems freely evolving over long times has a number of interesting applications, including high-precision measurements based on long-time atom interferometry. Microgravity platforms (such as drop-tower facilities, sounding rockets, the International Space Station and dedicated satellite missions) offer a natural environment where such long times can be reached with compact setups in free fall. In order to prevent the size of the atomic cloud from growing excessively, very low expansion rates are required. It is, therefore, necessary to prepare atomic ensembles with very low temperatures making use of laser cooling techniques, which are capable of reaching regimes of a few microkelvin. ...more

Israelian quantum physicist Prof. Nadav Katz is the new Hans Kupczyk guest professorship

15.12.2016: Ulm University president Prof. Weber has awarded the Hans Kupczyk Professorship to the renowned quantum scientist Professor Nadav Katz from Hebrew University of Jerusalem (Israel). Prof. Katz research focuses in the macroscopic quantum coherence and decoherence. The understanding and application of these quantum phenomena could pave the way for future technologies such as quantum computers. ...mehr

State Research Prize for Ulm's top researcher Prof. Jelezko

6.12.2016: the director of the Institute of Quantum Optics has received the State Research Prize for fundamental research in the field of "Diamond Quantum Technology". The award amounting to 100 000 Euro was conferred by Theresia Bauer, Minister for Science, Research and Arts, on 5th December during a ceremony in the Staatsgalerie Stuttgart....mehr

Trickling electrons - Close to absolute zero, the particles exhibit their quantum nature

9.11.2016: What would happen if an electric current no longer flowed, but trickled instead? This was the question investigated by researchers working with Christian Ast at the Max Planck Institute for Solid State Research in Stuttgart in collaboration with Joachim Ankerhold fromUlm University, as reported recently in Nature Communications. Their investigation involved cooling their scanning tunnelling microscope down to a fifteen thousandth of a degree above absolute zero. At these extremely low temperatures, the electrons reveal their quantum nature. The electric current is therefore a granular medium, consisting of individual particles. The electrons trickle through a conductor like grains of sand in an hourglass, a phenomenon that can be explained with the aid of quantum electrodynamics. ...mehr

Record participation in the "Highlights der Physik" in Ulm

3.10.2016: the 16th edition of "Highlights der Physik" was with 60.000 visitors the most succesfull so far. Under the motto "Microcosmos", the scientific festival presented the latest findings in current reserch in bio-quantum physics at the Ulm Münsterplatz from 27th September until 1st October....mehr
