Poster title: Higher Dimensional Representations of Qudits
Author: Dr. Renate C.-Z-Quehenberger (Vienna Emergent Systems Group, the Institute for a Sustainable Information Society (GSIS), Vienna, Austria)
Abstract: In memory of Peter Weibel and Helmut Rauch, who supported the FWF/PEEK project Quantum Cinema—a Digital Vision (2010–2013), during which the 3D animated visualisation of five- dimensional/ten-dimensional space was successfully completed (as shown below). The previously presented representation of entangled quantum states by means of a Boolean intersection of the 3D representation of the Penrose kite dart tiling (E±) derived from Mermin’s Magic Pentagram (2017, published in 2022) will be elucidated in a more illustrative way by putting it into the context of spin network theory, spin foam models, and loop quantum gravity. Based on this hyper-Euclidean quantum geometry, an attempt to visualize quantum bits in proportion (up to qudits in d = 16) is presented in the same framework within higher-dimensional-space configurations embedded into Poincaré dodecahedral space.

Poster title: Temporal Witnesses of Non-Classicality in a Macroscopic Biological System
Author: Dr. Giuseppe Di Pietra (University of Oxford, Oxford, England)
Abstract: Exciton transfer along a biopolymer is essential for many biological processes; for instance, light harvesting in photosynthetic biosystems. We apply a new witness of non-classicality to this phenomenon to conclude that, if an exciton can mediate the coherent quantum evolution of a photon, then the exciton is non-classical. We then propose a general qubit model for the quantum transfer of an exciton along a biopolymer chain, also discussing the effects of environmental decoherence. The generality of our results makes them ideal candidates with which to design new tests of quantum features in complex biomolecules.
