Collective defense of honeybee colonies: experimental results and theoretical modeling
Andrea López-Incera, Morgane Nouvian, Katja Ried +2
Social insect colonies routinely face large vertebrate predators, against which they need to mount a collective defense. To do so, honeybees use an alarm pheromone that recruits ne…
Development of swarm behavior in artificial learning agents that adapt to different foraging environments
Andrea López-Incera, Katja Ried, Thomas Müller +1
Collective behavior, and swarm formation in particular, has been studied from several perspectives within a large variety of fields, ranging from biology to physics. In this work,…
How a minimal learning agent can infer the existence of unobserved variables in a complex environment
Katja Ried, Benjamin Eva, Thomas Müller +1
According to a mainstream position in contemporary cognitive science and philosophy, the use of abstract compositional concepts is both a necessary and a sufficient condition for t…
Why initial system-environment correlations do not imply the failure of complete positivity: a causal perspective
David Schmid, Katja Ried, Robert W. Spekkens
The common wisdom in the field of quantum information theory is that when a system is initially correlated with its environment, the map describing its evolution may fail to be com…
Modelling collective motion based on the principle of agency
Katja Ried, Thomas Müller, Hans J. Briegel
Collective motion is an intriguing phenomenon, especially considering that it arises from a set of simple rules governing local interactions between individuals. In theoretical mod…
Transmitting qubits through relativistic fields
Robert H. Jonsson, Katja Ried, Eduardo Martin-Martinez +1
Wireless communication derives its power from the simultaneous emission of signals in multiple directions. However, in the context of quantum communication, this phenomenon must be…
Quantum to classical transitions in causal relations
Katja Ried, Jean-Philippe W. MacLean, Robert W. Spekkens +1
The landscape of causal relations that can hold among a set of systems in quantum theory is richer than in classical physics. In particular, a pair of time-ordered systems can be r…
Quantum-coherent mixtures of causal relations
Jean-Philippe W. MacLean, Katja Ried, Robert W. Spekkens +1
Understanding the causal influences that hold among parts of a system is critical both to explaining that system's natural behaviour and to controlling it through targeted interven…
Inferring causal structure: a quantum advantage
Katja Ried, Megan Agnew, Lydia Vermeyden +3
The problem of using observed correlations to infer causal relations is relevant to a wide variety of scientific disciplines. Yet given correlations between just two classical vari…
Entanglement entropy of a scalar field across a spherical boundary in the Einstein universe
Katja Ried
A scalar field in the ground state, when partially hidden from observation by a spherical boundary, acquires entanglement entropy proportional to the area of the surface. This…
