Diamonds, the best friends of quantum science - Quantum state measured in diamonds for the first time

21.02.2019: with the help of artificial diamonds, an international research team succeeded in taking another important step towards the high-tech application of quantum technology: for the first time, scientists were able to electrically measure the quantum state of a single qubit in diamonds. A qubit is considered the basic unit of quantum information. The results of the study, which was coordinated by the University of Ulm, were recently published in the renowned scientific journal Science ...more

Lithium atoms on the move - SALVE provides sensational insights into mini batteries

27.11.2018: You can call it simply a sensation, what has been achieved by scientists from Stuttgart, Ulm and Dresden. Using the Sub-Angstrom Low-Voltage Electron microscope (SALVE), they were able to show in atomic resolution how lithium ions behave during electrochemical loading and unloading processes. They have thus demonstrated how reversible lithium absorption takes place in a nano-cell that consists of only one double layer of graphene. These results, which are highly relevant for battery research, were recently published in the journal Nature   ...more

Quantum research for outer space New DLR Institute of Quantum Technologies in Space Applications in Ulm

12.11.2018: The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is setting up an institute in Ulm on the subject of quantum technologies in space applications (DLR-QT). The aim of DLR-QT is to develop next-generation precision instruments that can be used for navigation, communication as well as Earth observation and weather observation in space. In close cooperation with industry, DLR-QT will build a bridge between basic research and application. The institute has an annual budget of around €11 million at its disposal for this purpose, 90 percent of which is funded by the federal government and 10 percent by the state government of Baden-Württemberg ...more

The Carl Zeiss Foundation has gone ahead and already bestowed several millions of funding on the research project ‘TQuant’, in which findings of quantum science are being transferred to applications. ...more

Quantum physicists achieve entanglement record

11.4.2018: Entanglement is of central importance for the new quantum technologies of the 21st century. A German-Austrian research team is now presenting the largest entangled quantum register of individually controllable systems to date, consisting of a total of 20 quantum bits. The physicists in Innsbruck, Vienna and Ulm are pushing experimental and theoretical methods to the limits of what is currently possible. ...more

Topping-out ceremony of the "Centre for Quantum Biosciences"

27.11.2017: "The quantum sciences give us completely new insights into the world of biological systems. The innovative technology at the ZQB in Ulm creates the preconditions for researchers from physics, chemistry and molecular medicine to be able to explore new approaches for the development of drugs and biomaterials", emphasized Ulrich Steinbach, head of the Ministeriums für Wissenschaft, Forschung und Kunst (MWK) at the topping-out ceremony of the new research building. The potential of quantum technology is not yet exhausted and the second quantum revolution is imminent ...more

New residence for the SALVE Microscope

12.10.2017: For the first and to this day only low-voltage transmission electron microscope (TEM) with twofold aberration correction a new building far enough from the new tram line in Oberberghof was built. The microscope ispart of the SALVE research project. SALVE stands for Sub-Ångström Low-Voltage Electron microscopy and is the acronym for a research initiative that was launched in 2009 at Ulm University with the purpose to develop a particularly material-friendly technology for electron-microscopic imaging with atomic-scale resolution ...more

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"

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

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
