Aspelmeyer Group  
Team The main research objective of our group is to investigate quantum effects of nano- and microscopic systems and their implications for the foundations and applications of quantum physics. We apply and develop quantum optics methods to achieve control over motional states of these systems in the quantum regime. From a fundamental perspective, our goal is to gain access to a completely new parameter regime for experimental physics with respect to both size and complexity. We are particularly interested in the perspectives for studying the interface between quantum physics and gravity using quantum optical control over the motion of increasingly massive solids. From an application perspective we are investigating nano- and micromechanical systems in novel sensing and transducing architectures, for example as photon-phonon interface for quantum information processing or as inertial sensor for measuring weak gravitational forces. Our current activities are centred around the following topics: Quantum Controlling Levitated Systems Measuring Small-Scale Gravitational Forces Funding Agencies:  
Ursin Group  
Team Funding Agencies: Quantum Physics and Quantum Communication The Ursin group’s research interest focuses on “the essence of quantum physics”, as Erwin Schrödinger put it: Quantum Entanglement. We experimentally investigate quantum optical effects and quantum information processes. The creation, manipulation and detection of entangled photons and all of its applications are our expertise. Quantum Cryptography One of the most important applications of quantum optics is the promise of unconditionally secure communication. By exploiting the strange properties of quantum states, especially entangled photons, one can create an unbreakable cryptographic key between two users ("Quantum Key Distribution", QKD). The Ursin group is on the forefront of this state-of-the-art research field. Entanglement as resource The unintuitive properties of entangled photons are the fundamental principle not only of quantum communications, but also quantum sensing and fundamental quantum optics research. In these research fields, we investigate sensitive quantum interference effects in different environments.  
Mission Statement  
The Institute for Quantum Optics and Quantum Information – Vienna (IQOQI-Vienna) of the Austrian Academy of Sciences conducts theoretical and experimental research on the foundations of quantum physics, quantum information and space-time physics, and explores new possibilities for the construction of devices for quantum communication and quantum computing. IQOQI-Vienna brings an information-theoretic perspective and a foundational focus into physics questions, aiming at better comprehending quantum physics, combining it with other physical theories like General Relativity and opening up new avenues in quantum technology.  
Bits of History  
"A knowledge of the historic and philosophical background gives that kind of independence from prejudices of his generation from which most scientists are suffering." (Albert Einstein) Bits of History is the history blog of IQOQI-Vienna. Its aim is to popularise the outstanding historical legacy of physics in Vienna, in order to emphasise the connection between the present physics research and its historical roots. Bits of history features short stories authored by professional historians and scientists, accompanying and contextualising visual archival material representative of the Viennese physics milieu of the past, such as original letters and historical photos.   
Vienna Quantum Cafe  
The IQOQI Blog Vienna Quantum Café is the science blog of IQOQI-Vienna. The name refers to the culture of Viennese coffeehouses, also recognized as "Intangible Cultural Heritage" by UNESCO, as places of informal cultural exchange and discussion where new ideas emerge. The blog focuses on two areas: research ethics, including for instance current discussions on issues of scientific publishing, science management or science communication, and discussions communicating the significance and potential of foundational research in quantum physics and quantum information.  
YIRG - Young Independent Researcher Group  
Team The YIRG will focus on the following topics: Causality in physical theories is the research focus of the YIRG. We study the boundary of the theoretically possible correlations as well as of information processing. This boundary is approached from two sides: What are the limits under the assumption of causality, and how do these limits translate when we relax the assumption? Furthermore, we ask for conditions from which causality emerges. Emergence of causal order in quantum theory and beyond Information processing in theories with and without definite causal structure Contact: yirg@oeaw.ac.at  
Huber Group  
Team Quantum Information and Thermodynamics Our group aims to understand the role that information plays in the process of learning about and manipulating our physical environment.  
Rupert Ursin  
Rupert Ursin Group Leader Ursin Group (+ 43) 664 8847 6595 rupert.ursin@oeaw.ac.at Curriculum Vitae Publications Google Scholar Publication List Research Gate Researcher ID ISI Web of knowlege Dr. Rupert Ursin is a group leader and senior scientist at the IQOQI. His main field of research is to develop quantum communication and quantum information processing technologies, mainly for free-space, but also for fibre-based systems. The scope of his work ranges from near term engineering solutions for secure key sharing (quantum cryptography) to more speculative research (de-coherence of entangled states in gravitational fields). Experiments on quantum communication and teleportation using entangled photon pairs is also among his interests, with the long- term goal of a future global quantum network based on quantum repeaters. He has been experimentally active in numerous international collaborations in Germany, Italy, Spain, USA as well as in China and Japan. Lead several ESA funded projects as well as on the national and EU level. These allowed him to perform highly recognized experimental studies e.g. on a 144 km free-space link between La Palma and Tenerife [1] (cited more than 450 times). His group is performing time-energy entanglement distribution over a turbulent atmosphere just recently [5]. To date he and his publication recived several international awards and prizes. He was invited to several prestigious conferences to deliver talks (e.g. IEEE, SPIE, QCMC and others) and serves to important conferences as a program committee member e.g. ICSOS, SPIE, QCrypt and others. He currently holds a guest professorship at the University of Science and Technology (USTC) in Shanghai, China. Research interests Research interests include fundamental physics experiments on topics related to quantum optics and quantum information and their applications. Focus on the development of technologies required to perform space-based experiments concerning quantum information technologies. Numerous project partners in various fields (academic as well as industrial) together with national space agencies and the European Space Agency (ESA) are involved in this project. Contacts to international collaborators in Japan, China and USA are important partners to perform quantum communication on a global scale.
