We show that if a massive body is put in a quantum superposition of spatially separated states, the mere presence of a black hole in the vicinity of the body will eventually destroy the coherence of the superposition.

Increasing curiosity about science and research among young people is the most important goal of the European Researchers' Night. Researchers from IQOQI-Vienna support this aim and presented their research topics.

Most of our observations that characterize space and time are expressed in terms of non-local, bi-tensorial objects such as geodesic or null intervals between events and two-point (Green's) functions.

The typical practitioner of physics is not exposed to the history of their field very much.

In face of ongoing difficulties to find experimental support for research programs related to quantum gravity, one remains with non-empirical methodologies for theory advancement.

The field of indefinite causal order born as a tentative to generalize quantum mechanics to a theory with no predefined causal structure, aiming to find a consistent framework for a quantum gravity theory. One key feature of this formulation is the…

The realization of the physicality of information is one of the biggest revolutions of modern physics. In this path, a central role was played by Maxwell's demon, a thought experiment initially introduced to challenge the universal validity of the…

We argue that there exists an operational way to establish the objective reality of the notions of space and time.

In this talk I will first show how the phenomenology of quantum interference that is traditionally regarded as problematic does not pose a challenge to the classical worldview.

After decades, we still lack a proper understanding of the quantum nature of gravity. Nonetheless, we have already seen many theoretical hints that gravity does not easily fit in the quantum mechanical framework.
