Physicists of all fields and physics students are invited to join the Ehrenfest Award online talk on Monday, February 8, 6 pm CET.

This is an introductory talk about the second law of thermodynamics and the associated problem of finding a meaningful notion of (thermodynamic) entropy; (mostly) viewed from the perspective of quantum many-body systems, ultracold atoms and open…

I will talk about atomic clocks at the interface of quantum theory and gravity, and how they can be used to shed light on tests of the quantum equivalence principle defined in [1], namely a generalization of the ordinary equivalence principle that…

Vienna Quantum Foundations Conference Sept 7th – 10th, 2021

Stochastic process models serve to describe a wide variety of natural and social phenomena, such as the weather, traffic congestion, and atomic decay. The simulation of stochastic processes provides valuable information about the dynamics of complex…

I am proposing a brainstorming about a major research direction that is not being pursued (in my opinion), even though seeds of it are present in various works.

In several quantum information tasks, notably in the fields of quantum communication, cryptography, and sensing, classical information is encoded not in a quantum state but in an optical mode.

To establish operational reference frames for time, one requires physical clocks that periodically send signals to observers. The synchronisation between the various signals determines the quality of the time reference.

We introduce a software package that allows users to design and run simulations of thought experiments in quantum theory. In particular, it covers cases where reasoning agents are modelled as quantum systems, such as Wigner's friend experiment.

Designing encoding and decoding circuits to reliably send messages over many uses of a noisy channel is a central problem in communication theory. When studying the optimal transmission rates, it is usually assumed that these circuits can be…
