The paper “Ultrasensitive magnetometer using a single atom” was selected as a PRL EDITORS’ SUGGESTION

High-sensitivity magnetometer using a single atom
Ultrasensitive magnetometer using a single atom.

The gist of it

The development of highly sensitive methods for the detection of minute fields lies at the heart of quantum metrology and has, over the history of science, led to many discoveries. This motivates the continuous drive towards the development of ever more sensitive metrology methods. Of particular interest in this context are atoms and ions that are trapped in ultra-high vacuum as they can be isolated to a remarkable degree from environmental influences. Still noise will impose limitations and needs to be addressed.

We demonstrate a novel method for sensing magnetic fields and demonstrate that it can achieve the best sensitivity ever realized for a single trapped atomic particle and it can do so over a broad range of frequencies. State-of-the-art magnetometers reach their best sensitivity in a limited frequency-band or do not work at all (for all practical purposes) outside a certain frequency range. The type of magnetometer introduced here could be used to detect fields from direct-current to the gigahertz regime – an unprecedented range of frequencies – using an atom confined to a nanometer-sized region in space. Moreover, the magnetometer is essentially immune against magnetic disturbances and reaches a sensitivity close to the standard quantum limit.

The HYPERDIAMOND project – Horizon 2020

logo_Hyperdiamond_transparentEC LOGO

The HYPERDIAMOND project, coordinated by Martin Plenio, was chosen as one of the eight projects (out of 390) selected in the Horizon 2020 call Personalizing Health and Care: Development of new diagnostic tools and technologies: in vivo medical imaging technologies.

HYPERDIAMOND marks the first translational research and innovation project coordinated by the Institute of Theoretical Physics (ITP). Unlike the previous EU projects of the institute which were research focused, HYPERDIAMOND is a research and innovation project aiming at developing a new technology for improving medical imaging, in particular the imaging of targeted molecules and processes in vivo.

Building on recent breakthroughs in molecular hyperpolarization, which proved > 10,000-fold increase in sensitivity on conventional magnetic resonance imaging (MRI), HYPERDIAMOND will bring radical advances from the fields of quantum physics and nanotechnologies to develop a technology suitable for widespread medical use. Leveraging unique properties of NV centres in diamonds, combined with diamond surface and organic chemistry and dynamic nuclear polarization protocols, the HYPERDIAMOND project will bridge the gap between the lab and the medical setting, making two new technological devices compatible with medical imaging requirements.

In the project ITP will develop novel dynamic nuclear polarization protocols which will serve as the basis for the developed technology, model the dynamics of nuclear relaxation in nanodiamonds, and support the experiments with theory and simulations. Moreover, one of the SMEs participating in the project, NVision Imaging Technologies GmbH, is a technology spin-off of Ulm University founded by Ilai Schwartz and Martin Plenio of the ITP, ITP alumni Alex Retzker and Fedor Jelezko from the IQO. NVision is building on the research performed at ITP and the Institute of Quantum Optics to bring novel imaging technologies to real-world applications.

ITP, together with three additional institutes in Ulm University, established a truly multidisciplinary team: combining leading research institutes and 3 SMEs, with expertise ranging from molecular imaging (Austrian Institute of Technology), NMR (Karlsruhe Institute of Technology), nanodiamond material science (François Rabelais University, Van-Moppes), theoretical and experimental quantum physics (University of Ulm, Hebrew University of Jerusalem, NVision Imaging Technologies), diamond surface bio-chemistry (UULM), small animal MR imaging (Hadassah Medical Center, UULM), pre-clinical expertise (UULM, Hadassah, AIT) and medical devices and magnetics production (Kanfit).

This April we have celebrated the 1st Table Tennis Tournament of the ITP. It has been an amazing event where many institute members have taken part, either as a participant or as a captivated audience. We had four rounds, each of them full of incredible matches and breathtaking shots that will be remembered forever and ever.

After three weeks of thrilling expectation Ish Dhand has won the finals, obtaining the certificate of the Absolute Winner, donning the victory crown, and gaining the honorable title of PingPong King! Congratulations again!!!

Given the success of the first edition, we are already planning a Table Tennis League while we wait for the second tournament!

Many thanks to Pelayo for organizing it!

Faculty Kolloquium and visit to the ITP

We were most happy to welcome Stephanie Wehner (TU Delft) to visit the Institute and deliver the last Faculty Kolloquium of the year 2015. Stephanie presented a very nice and pedagogical talk on the foundations of quantum thermodynamics. She also discussed her recent work on the revision of the concept of Carnot maximal efficiency for quantum thermal machines, which does not only depend on the temperature of the heat reservoirs. These are results in collaboration with Mischa Woods, a former PhD student of the Institute. You can read all details in arXiv:1506.02322

There was also time for discussions Followed by a hearty Schwabian dinner of Goose and Rotkraut at the Zunfthaus in the Fischerviertel to celebrate the Christmas season.

Stephanie was lucky with the weather and also brave enough to climb the tower of the Ulmer Münster (768 steps to reach the top) before catching the train home. The Münster is the one of the five tallest structures to be completed last century, with the steeple of almost 162 meters, the tallest church in the world. Below you can see two fantastic pictures she took in her ascent.
