The CoQuS Program

The Vienna Graduate Program on Complex Quantum Systems (CoQuS)  provides graduate education dominantly through intense research training and through advanced courses in one of the most active fields of modern physics.
In particular in recent years, many new ideas for future quantum technologies could already be demonstrated in the lab.

The Vienna doctoral program on Complex Quantum Systems offers PhD research and training opportunities in the following fields:

  • Quantum Nanophysics & Molecular Quantum Optics
  • Quantum Foundations
  • Quantum Information on the Nano- & Microscale 
  • Quantum Optics Theory
  • Nano-Fiber Photonics & Quantum Optics 
  • Cold atoms and atom chips
  • Quantum-enhanced measurement & metrology
  • Quantum cascade lasers & quantum dots
  • Many-body quantum theory
  • Quantum information sciences & quantum computation
  • Quantum Information and Foundations of Physics
  • Quantum effects in biological systems
  • Theoretical Atomic, Molecular, and Optical Physics
  • Relativistic quantum information & metrology
  • Quantum Integrated Devices
  • Non-Hermitian Quantum Physics and Photonics

The program provides the opportunity for highly gifted students to obtain a broad and interdisciplinary education in many of these fields and to prove themselves in cutting edge research.

The following faculty members and associated members will serve as thesis supervisors:

  • Prof. Markus Arndt, University of Vienna
  • Prof. Markus Aspelmeyer, University of Vienna
  • Prof. Caslav Brukner, University of Vienna
  • Ass. Prof. Peter Rabl, Vienna University of Technology
  • Prof. Arno Rauschenbeutel, Vienna University of Technology
  • Prof. Jörg Schmiedmayer, Vienna University of Technology
  • Prof. Karl Unterrainer, Vienna University of Technology
  • Prof. Frank Verstraete, University of Vienna
  • Assoc.Prof. Philip Walther, University of Vienna
  • Prof. Anton Zeilinger, University of Vienna

Associated members:

  • Prof. Johannes Fink, Institute of Science and Technology (IST Austria) 
  • Dr. Ivette Fuentes, University of Vienna
  • Prof. Mikhail Lemeshko, Institute of Science and Technology (IST Austria)
  • Prof. Stefan Rotter, Vienna University of Technology
  • Prof. Thorsten Schumm, Vienna University of Technology

The doctoral program is closely linked to several FWF funded and ERC excellence programs, to the Austrian Academy Institute of Quantum Optics and Quantum Information (IQOQI), to several European networks and many international collaboration projects.
We seek to increase the percentage of women in physics. The CoQuS faculty therefore explicitly encourages qualified female students to apply.


Employment Details

The Vienna graduate program provides financial support for up to three years. Doctoral students admitted to the CoQuS program will have a regular employment at their hosting University.  
The employment includes:

  • A gross salary around 2000€/month (this incl. tax & health benefits)
  • A tuition waiver

The graduate program will also provide support for

  • Travel to scientific work shops, schools and conferences
  • Exchange program to partner universities 
  • Soft skill trainings & language courses

The number of places in this excellence program is limited. The faculty members will select new students according to their academic excellence,  scientific achievements and expected potential for future research.
