The University of Vienna is consistently developing the campus as a diverse location for research, study, and exchange. With the **Campus 2030+ project**, measures are being implemented step by step to strengthen the campus as a working and learning environment for students and staff, preserve it as a green oasis in an urban space, and make it visible as a place where science and society meet.\
A central project in this development is the **Quantum Cube,** which is being built in Courtyard 2 of the campus. This is a new research building for quantum optics, nanophysics, and information. The new building is necessary because highly sensitive experiments can no longer be carried out with precision at the previous location on Währinger Straße/Boltzmanngasse due to traffic influences and the expansion of the U5 subway line.

*Note: The schedule corresponds to the current planning status and is dependent on the tendering process, the availability of trades and unforeseeable building site risks.*
##### Disturbances in Courtyard 2 and Courtyard 3
Access to the construction site is via Van Swieten Gasse and then via Courtyard 3. Large deliveries will be announced in advance and accompanied for safety reasons. A construction crane will be erected in Courtyard 3 to lift materials onto the construction site in Courtyard 2. There is a storage area in on the adjacent lawn in Courtyard 3 where materials are unloaded and then lifted by crane onto the construction site in courtyard 2.
A protected, covered walkway will be set up in the crane's swivel area to ensure the safety of pedestrians.
The construction site facilities and site containers are located on the meadow in courtyard 2. Access to the adjacent buildings will remain open throughout the construction period and can be reached via secure walkways. The construction site itself will be clearly demarcated by a three-metre-high fence.
##### Noise and dirt caused by building site
The noisiest phase of construction is scheduled for summer 2026 (excavation work and construction of the reinforced concrete core). There may also be periods of increased noise during the delivery and lifting of prefabricated elements for the above-ground construction. **The construction schedule is designed so that particularly noisy activities take place outside of lecture and examination periods as far as possible.** However, occasional noise pollution cannot be completely avoided. Those responsible for the project will endeavour to communicate foreseeable disruptions to the affected institutes at an early stage. The aim is to implement the project as considerately as possible; specific coordination with the contractors will take place as planning progresses.
Overall, **dirt pollution should remain limited**, as no demolition work is involved and no unusually high levels of dust are expected during the excavation work. The construction site area will be cleaned regularly and is clearly demarcated by a three-metre-high fence, which also minimises the spread of dirt. Should there nevertheless be an increased need for cleaning, please notify us at [campus(at)univie.ac.at](#).
##### Tree protection
Protecting the Judas tree (a natural monument) directly adjacent to the construction site is a high priority. In consultation with the experts on tree protection and the responsible specialist departments, a protective wooden fence will be erected covering an area two metres beyond the crown edge. This is to ensure that no root damage or impairment to the tree occurs during the construction work.

The University of Vienna is aware of the challenges posed by constructing a new building on a lawn that has previously been used primarily as a recreational area. Therefore, the focus is on the balanced development of the entire campus grounds. In contrast to the new sealing in Courtyard 2 (approx. 400 m²), other areas on the grounds will be unsealed and redesigned for the various users on campus.
In the centrally located and heavily used **Courtyard 1**, the complete unsealing of the former outdoor dining area of the pizzeria will create a **new open space of around 600 m²** from 2026. Non-commercial green areas and recreation zones are planned there.
The former restaurant premises of the pizzeria (or former Uni-Bräu) are planned to be converted into **student spaces** from 2027 onwards. The aim is to create consumption-free recreation and study areas for students.
Other spaces that will become available – such as the former Facultas branch at the Spitalgasse/Alser Straße entrance – are earmarked for internal university use: the establishment of **centrally managed seminar rooms** that can be used for events during the lecture-free period will be implemented from 2026.

##### What is the Quantum Cube?
The Quantum Cube is a new research building at the University of Vienna, designed specifically for experimental quantum physics at the Faculty of Physics. The new building will be constructed in Courtyard 2 of the University of Vienna campus from 2026 onwards.
##### Why is the new building necessary?
**Quantum physics** is a key research focus at the University of Vienna and an area in which Austria plays a leading role internationally. In order to secure and further expand this position, infrastructure is needed that meets the requirements of modern science. The planned new building on the Campus, on a site that has always been designated for construction and is owned by the University of Vienna, will create the conditions necessary to conduct high-precision experiments in an optimal environment and continue research at the highest level.
The current location of the laboratories at Boltzmanngasse 5, a historic building from the early 20th century, no longer meets the technical and spatial requirements of quantum research. Factors such as ventilation, vibrations, magnetic fields and structural limitations make it difficult to carry out sensitive experiments. The new building offers a tailor-made solution: a modern laboratory building that provides a disturbance-free environment and the necessary technical equipment.
Research at this level is important not only for the scientific community, but also for society and the economy. Basic research and ‘blue sky research’ are the basis for technological innovations that create new opportunities in the long term and drive progress forward. In order to be successful in the international competition for the best talent and ideas, a modern infrastructure is essential.
##### Why is the building being constructed on the Campus site?
Highly sensitive quantum research places stringent demands on the site in terms of vibrations, oscillations and electromagnetic influences. Based on these requirements, the University of Vienna (Space and Resource Management / RRM) investigated alternative options with the involvement of experts. The result: the campus location is the most suitable. The area in question has a building permit (independent of the Quantum Cube project).
##### What is being researched at the Quantum Cube?
[Quantum physics](https://quantum.univie.ac.at/) is one of the most successful and precise theories ever developed by humankind. It forms the basis for numerous technological innovations that have become an integral part of our everyday lives – from lasers and semiconductors to superconductors and atomic clocks to quantum computers and quantum sensors.
Fundamental questions are being researched at the Quantum Cube. The experiments at the Quantum Cube open up new perspectives at the interface of quantum physics, (bio)chemistry and gravitational theory. They aim to explore the limits of our understanding of quantum mechanics and answer new scientific questions.
Research at the Quantum Cube is dedicated to fundamental experiments that may inspire new quantum technologies in the long term, particularly in the field of sensor technology. The Quantum Cube is thus a place where quantum physics is researched in its purest form – with the aim of better understanding the fundamental principles of nature and opening up new avenues for future innovation.
##### Who will use the new building?
Around **50 researchers from the Faculty of Physics** will work in the Quantum Cube and receive training for the future. The building has been designed to be sustainable and to be used for many decades to come. It will therefore not only offer optimal conditions for current research groups, but will also be available to future generations of scientists conducting sensitive experiments. The Quantum Cube is thus a long-term contribution to strengthening basic research at the University of Vienna in a highly competitive and growing international field of research.
Due to the safety requirements for high-precision research, there are **no publicly accessible areas** in the Quantum Cube.
##### What will happen to the vacant spaces on the Campus?
In 2025, several previously leased areas on the Campus became vacant. In accordance with campus development guidelines, these will be reserved for internal university use in future.
Specifically, this concerns:
- the premises of the former pizzeria in Courtyard 1 (including outdoor dining area and building),
- storage areas of the former “Stiegl Ambulanz” at the Sonnenfels Gate,
- and the former Facultas-branch on the corner of Spitalgasse/Alser Straße.
The plan is to set up new **consumption-free student spaces** in Courtyard 1 with a small adjoining bistro with a few seats. The construction work on the former outdoor dining area and the creation of a new open space will be carried out in 2026.
However, due to the extensive renovation work required on the restaurant areas returned by the tenant, the interior renovations can no longer be included in the 2026 budget. In order to avoid prolonged vacancy, possibilities for interim use will be examined in 2026.
The former Facultas premises are earmarked for the establishment of two centrally managed seminar rooms. The planning and preparatory work for this will start in the second half of 2026. Here, too, extensive adaptation and renovation work is necessary.
The relocation of the porter's lodge to the passageway at Alser Straße 4 / Hof 1 and the establishment of a parcel collection point are also planned, but implementation is not expected until 2027 at the earliest.
##### What will the announced student spaces in Courtyard 1 look like?
The design of the **student spaces** is based on proven examples from the university (such as [Porzellangasse 4](https://studieren.univie.ac.at/studieren-und-leben-wen-frage-ich-bei/student-space/student-space-porzellangasse-4/), [Währinger Straße 29](https://studieren.univie.ac.at/studieren-und-leben-wen-frage-ich-bei/student-space/muster-student-space-waehringer-strasse-29/)). As part of the Campus Working Group, student representatives are also invited to participate in the planning of the premises.
##### What should the new open space in Courtyard 1 look like?
An initial concept for the redesign of the open space in Courtyard 1 was developed at the end of 2025 by the landscape architecture firm **Carla Lo,** which was commissioned to develop the campus open space. The aim was to take into account as far as possible the wishes and suggestions put forward during the brainstorming sessions of the Campus 2030+ working group, including additional seating, consumption-free green spaces, access to drinking water and shaded recreation areas.
The concept was presented to the Campus Working Group in November 2025 and put up for discussion. The working group was invited to contribute comments and additions.
Based on the adapted concept, the plan is to proceed with the tender process and subsequent construction in 2026.

##### How can students and staff participate in shaping the Campus?
The design of the campus grounds is being carried out in collaboration with the landscape architecture firm commissioned to develop the site and the Campus 2030+ working group, which includes representatives from both the student body and the institutes located on campus. For more information about the working group, please contact [campus(at)univie.ac.at](#).
- The campus is primarily a **place of work and study** for university members. The further development of the campus will ensure and improve the quality of work (places).
- The campus is a **tangible green oasis** with a high quality of life and space for biodiversity-friendly design and sustainability measures by the University of Vienna.
- The campus is a **place of exchange** between the university and society: through open spaces and recreational areas, catering facilities and playgrounds, visibility of the institutes, events and formats such as “Gates of Remembrance” or new exhibition concepts for outdoor spaces.
Key decisions:
- The **main use remains** with the humanities and cultural studies faculties.
- **Own use instead of external use**: space that becomes available is used primarily by the university itself.
- **Spaces for meeting and communication** are at the heart of new usage concepts.
