Homodyne a DJ Quantum art show

The art show ‘Homodyne’ premiered on the 30th of June, 2023. The performance results from an interdisciplinary collaboration and explores how quantum entanglement and emergent properties of space and time affect the ontology of bodies in performance art.

We will discuss an interpretation of physics named “potentiality realism”. This view, which can be applied to classical as well as to quantum physics, regards potentialities (i.e. intrinsic, objective propensities for individual events to obtain) as elements of reality, thereby complementing the actual values taken by physical variables. This allows one to naturally reconcile realism …

Sejny summer institute 2023

6-16 July 2023 The Sejny Summer Institute is addressed to curious junior researchers (graduate students, post-docs, etc) from different areas of the foundations of physics (mathematics, theoretical and experimental physics, computer science, philosophy), willing to engage in active and open-minded discussions. Far from the format of traditional conferences and subject-specific workshops, the Sejny Summer Institute …

Institut National du Service PublicCan French Administration be more sexy than Quantum Gravity?

After ten years in science, wandering between quantum gravity and quantum foundations, I have entered l’Institut National du Service Public (ex-ENA) to pursue a career as top executive in the French administration. In this unusual talk, I will offer my personal take on the following questions: – Is there a life after academia? – What …

Markus Müller
IQOQI Vienna How spacetime constrains the structure of quantum theory

Modern physics has taught us that space and time are described by different “theories of geometry” in different regimes, from Galilean spacetime in Newtonian mechanics to semi-Riemannian manifolds in general relativity. In a very similar, but less well-known sense, classical probability theory and quantum theory (QT) are special cases in a large landscape of “theories …

Sean Carroll
Johns Hopkins UniversityExtracting the Universe from the Wave Function

Quantum mechanics is a theory of wave functions in Hilbert space. Many features that we generally take for granted when we use quantum mechanics — classical spacetime, locality, the system/environment split, collapse/branching, preferred observables, the Born rule for probabilities — should in principle be derivable from the basic ingredients of the quantum state and the …

Abhay Ashtekar
Pennsylvania State UniversityThe many faces of photons

In the standard Fock representation, the 1-photon Hilbert space is spanned by positive frequency, source-free solutions of Maxwell’s equations. The quantum information they carry corresponds precisely to the two radiative modes of the Maxwell fields.  However, this Fock representation is inadequate in a number of physical situations involving sources, and one then has to use appropriate non-Fock representations. …
