Congratulations, Jorge, to the birth of your daughter, Alejandra!
We hope you have a joyful and healthy journey ahead and we are looking forward to Alejandra’s first visit to the institute!
Recently, Ilai and Martin, in a collaboration with Liam McGuinness and Fedor Jelezko and their team, published their work in Science. In a joint theoretical and experimental work NMR signals of nanoscale samples were measured in a setup that is capable, in principle, of resolving chemical shifts and J-coupling which are essential quantities to identify molecules or determine their structure.

Our work on the role of the interplay of quantum dynamics and the environment, notably vibronic coupling, is reported upon in a science special in the Frankfurter Allgemeine Sonntagszeitung, a leading German weekly. It also explains our recent collaboration with the Christoph Lienau to show that vibronic coupling that we introduced to quantum biology is also active in organic photovoltaics.

ITP and the Center of QuantumBioSciences is part of newly approved Collaborative Research Center 1279 on “Exploiting the Human Peptidome for Novel Antimicrobial and Anticancer Agents”. Our team contributes to the CRC with a project on hyperpolarized nanodiamond as contrast agents for cancer research. Funded initially for a period of 4 years the CRC may be extended for a duration of up to 12 years.
The work of the Institute on hyperpolarized magnetic resonance imaging was mentioned in a recent special on quantum technologies by The Economist: http://www.economist.com/node/21718308?frsc=dg%7Cc .
In our work, Ilai, Qiong, Benedikt, Pelayo, Janica and Martin are collaborating closely with our friends from the Institute of Quantum Optics to use diamond quantum technologies to create very strong nuclear spin polarization in nanoscale diamonds as well as metabolic molecules outside of the diamond substrate. As the signal in a magnetic resonance scanner is proportional to the polarization of the target, this has the potential to strongly enhance the imaging capabilities of MRI. Our dream is to use these ideas to revolutionize cancer imaging and hence improve its detection as well the assessment of treatment success. Supported by the EU Project HYPERDIAMOND we have made encouraging progress, but we want to go further. With our start-up NVision Imaging Technologies we are pursuing the translation of this quantum technology to the real world !
Jorge Casanova wins a “Forschungsbonus”, https://www.uni-ulm.de/in/fakultaet/in-detailseiten/news-detail/article/forschungs-und-lehrboni-vergeben-psychotrauma-quanten-und-stochastik-forscher-sowie-innovative/, an award of the Ulm University for excellence in research, to recognize his work on the control of electron and nuclear spins in diamonds and trapped ions.
Well done Jorge !
While controlling a quantum system is a standard task nowadays, we are still far away from developing quantum computers, and one might wonder what is the difference between the two. Qualitatively the difference is that for quantum computing one needs to control quantum systems in a quantum way, using quantum systems instead of directly using the large apparata or (classical) electromagnetical fields that often are enough to control a quantum system directly. In this letter we make this idea precise by building a theory which allows us to quantify the usefulness of controlling a quantum system through a quantum system instead of using a classical one.

The gist of it
Cooling of atomic motion is an essential precursor for many interesting experiments and technologies, such as quantum computing and simulation using trapped atoms and ions. In most cases, this cooling is performed using lasers to create a kind of light-induced friction force which slows the atoms down. This process is often rather wasteful, because lasers use up a huge amount of energy relative to the tiny size of the atoms we want to cool. Here, we propose to solve this problem using a quantum absorption refrigerator: a machine that is powered only by readily available thermal energy, such as sunlight, as it flows through the device. We describe how to build such a refrigerator, and predict that sunlight could actually be used to cool an atom to nearly absolute zero temperature. The refrigerator works by trapping the sunlight between two mirrors, in such a way that every single photon makes a significant contribution to the friction force slowing the atom down. Similar schemes could eventually be important for reducing the energy cost of cooling in future quantum technologies.
