Levitated macroscopic particles exhibiting quantum mechanical effects are garnering increased attention as a means for sensing and testing the limits of quantum mechanics.

In their strongest usage, quantum reference frames have been described as referring to "the measurements performed by a superposed lab", "the perspective of a quantum particle", "the point of view of a superposed observer", etc. While exciting, these…

It is expected that a quantum theory of gravity will radically alter our current notion of spacetime geometry to account for quantum fluctuations. However, contrary to what was commonly assumed for many decades, these fluctuations could manifest in…

Diamonds containing nitrogen-vacancy centres are famous among physicists because of their use in quantum technologies.

Requiring that the causal structure between different parties is well-defined imposes constraints on the correlations they can establish, which define so-called causal correlations.

When, 100 years ago, the groundwork of modern quantum theory was laid in a series of memorable papers by the physicists of the Göttingen School, not everybody was enthusiastic about the highly abstract nature of their approach...

The international conference "Vienna Quantum Foundations Conference: Schrödinger Centenary" brings together experts from various fields of quantum information science.

In its minimal form, finite-dimensional quantum mechanics does not come with a preferred way of dividing the world into subsystems. A tensor-product factorization, whether into “system and environment” or into “field modes at different points in…
