The theory of decoherence is arguably among the greatest advances in fundamental physics of the past forty years

Recently, I introduced a non-perturbative quantization of impulsive gravitational null initial data. In this talk, I present the key results established thus far.

Quantum key distribution and other quantum 2.0 technologies are now being deployed in space.

Kochen-Specker Contextuality and Bell Nonlocality are central properties that forbid classical models to reproduce quantum results. They are usually seem as similar but distinct families of no-go theorems.

The Long Night of Research will take place on May 24, 2024 from 5 p.m. to 11 p.m. at over 200 exhibition venues throughout Austria. IQOQI Vienna is participating again and our researchers will be on site to explain their work and projects and answer…

The quantization of gravity is widely believed to result in gravitons -- particles of discrete energy that form gravitational waves. But their detection has so far been considered impossible.

The existence of incompatible measurements is often believed to be a feature of quantum theory which signals its inconsistency with any classical worldview.

One of the peculiar aspects of quantum theory is the existence of pairs of observables that cannot be measured simultaneously. Extracting information about one of the elements of the pair causes an irreversible disturbance on the other, making it…

Accessing the physical sector in quantum gravity models is a challenge, but also an important step towards analysing and testing such models.
