QuCoM experimentalists continue to hold regular online meetings every second Tuesday of every month. At both experiment sites, Leiden and Southampton, there are setups which are used to detect gravity with levitated masses. These experiments are cryogenic and involved advanced vibration isolation techniques. Leiden labs are using tantalum superconductors and asymmetric…

Quantum information scrambling (QIS), from the perspective of quantum information theory, is generally understood as local non-retrievability of information evolved through some dynamical process, and is often quantified via entropic quantities such…
A quantum state is said to be objective if multiple observers are able to recover information about the state and agree among themselves. This is in turn possible only if said information was encoded multiple times into the surrounding environment. In this paper, we show how it is not always possible for the observers to…

While the terms “redundancy” and “consensus” are often used as synonyms in the context of quantum objectivity, we show here that these should be understood as two related but distinct notions, that quantify different features of the quantum-toclassical transition. We show that the two main…
