Lastly, we discuss a possible violation of the weak equivalence principle due to the nongeodesic motion.

    Playing with Bob's toys to quantize gravity

    We show that it can also be used to describe SU(2) representation theory at the basis of the spin-network representation of quantum states of space. We recall the definition of Yutsis diagrams, a standard graphical calculus used in quantum chemistry and quantum gravity, and we show how it embeds within Penrose's binor calculus. Then we show how we can explicitly diagrammatically calculate 3jm, 4jm and 6j symbols with ZX-calculus. It has long been thought that quantum gravity ...

    For systems of higher dimensions (qudits), we will present interesting connections with modular arithmetic and the the different perspectives associated to the so-called qudit hypergraph states.

Second I will discuss for which cases the marginals determine the global state uniquely, either among all pure states or among all mixed states.

    Österreichischen Akademie der Wissenschaften (ÖAW) hat diese Kräfte nun erstmals im Labor nachgewiesen. Dafür haben die Forscher auf ein berühmtes Experiment des britischen Naturwissenschaftlers Henry Cavendish am Ende des 18. Jahrhunderts zurückgegriffen. 2 Millimeter große Goldkugel Noch zu Zeiten von Isaac Newton hat man geglaubt, dass die Schwerkraft astronomischen Objekten wie Planeten vorbehalten ist. Erst durch die Arbeiten von Cavendish (und vor ihm Nevil Maskelyne, ...
