I will discuss the rigid information geometry of quantum theory, tied to the apparently rigid form of the Born rule, and its necessary generalization in quantum gravity, together with experimental implications that involve intrinsic triple and higher…

In this presentation, I do not try to solve the measurement problem, but rather to properly formulate it.

In this talk I will discuss how modelling local, nonperturbative measurements in relativistic field theories has traditionally led to a choice between mathematical intractability and frictions with covariance and causality.

The recent development of technologies based on fundamental quantum physical phenomena such as superposition and entanglement adds new weight to the question whether nature may have found similar solutions.

Contextuality is a key distinguishing feature between classical and quantum physics. It expresses a fundamental obstruction to describing quantum theory using classical concepts. In turn, when understood as a resource for quantum computation, it is…

The concept of a "quantum reference frame" has been explored by physicists and philosophers working together as a way to make sense of the idea of quantum superpositions of space-times.

Einstein's general theory of relativity is based on the principle of equivalence - in essence, dating back to Galileo - which asserts that, locally, the effect of a gravitational field is equivalent to that of an accelerating reference frame, so that…

The setup of the Einstein-Podolsky-Rosen (EPR) paradox leads to an observer-dependent description of the quantum state from the perspective of quantum information theory.

We argue that the concept of signatures, which is prominently used in particle physics measurements, albeit widely neglected by philosophers, represents an important complement to the much-discussed concept of phenomena – not only in physics.
