General probabilistic theories in phase space, the harmonic oscillator and the hydrogen atom
We show that the framework of general probabilistic theories can be extended to describe continuous-variable theories on phase space and that the phase-space formulation of general probabilistic theories can include a generalized time-evolution.

Quantum Fisher Information and its dynamical nature
The importance of the quantum Fisher information metric is testified by the number of applications that this has in very different fields, ranging from hypothesis testing to metrology, passing through thermodynamics.

Realism, Intuitiveness, and the Scandal of Entanglement. Einstein and Schrödinger on EPR
Even though Einstein and Schrödinger were centrally important for the development of modern quantum physics, they never accepted quantum mechanics and its interpretation through the “Copenhagen School” as a satisfying foundational theory.

Onset of coherence in nonequilibrium condensates
In the first half of this talk, I will review the status of experiments on Bose-Einstein condensation of polaritons ("heavy photons"), including the transition from nonequilibrium behavior to true equilibrium behavior as their lifetime is increased relative to their thermalization time.

Paul Ehrenfest Best Paper Award for Quantum Foundations
We congratulate the authors of the publication "Quantum theory based on real numbers can be experimentally falsified": Marc-Olivier Renou, David Trillo, Mirjam Weilenmann, Thinh P. Le, Armin Tavakoli, Nicolas Gisin, Antonio Acín and Miguel Navascues

Quantum measurements and equilibration: modelling the emergence of objectivity via entropy maximisation
Textbook quantum physics features two types of dynamics: reversible unitary dynamics and irreversible measurements.

Interaction and Evolution in Classical Mechanics and in Quantum Mechanics, and Indefinite Causal Orders
I describe a few theorems that show that, in classical mechanics (Newtonian and Lagrangian mechanics), the intrinsic structure of the dynamics naturally distinguishes the concept of interaction from that of evolution, and, correlatively, position from momentum.

From Quantum in Pictures to practical Natural Language Processing, Music, and understandable AI.
This talk requires no particular technical mathematics background, as I will talk entirely in terms of simple pictures. These are the pictures of my new book, "Quantum in Pictures" [1], which is aimed at the teenage enthusiast, and pretty much everyone else too - the book had a more technical predecessor [2].

Causal Structure and the Delicacy of Holographic Arguments for Unitarity
I examine Marolf's influential argument for the unitarity of black hole evaporation based on what he calls a holographic argument for boundary unitarity.

Gravitationally induced decoherence vs space-time diffusion; testing the quantum nature of gravity
We consider two interacting systems when one is treated classically while the other remains quantum. Despite several famous no-go arguments, consistent dynamics of this coupling exist, and we derive its most general form.
