Quantum physics is the contested best description of the inanimate world but it leads to phenomena which are in radical conflict with our common sense perception of the world. While we have grown to accept this conundrum for electrons, neutrons or atoms it is intriguing to explore how the complexity of an object will influence the possibility of preparing it in genuine quantum states. We ask in particular how to enable quantum superposition experiments with the diverse set of biological nanomatter that nature provides, starting from simple vitamins, biodyes and amino acids of polypeptides and proteins to self-replicating molecules. This is an ongoing journey on a road with many branches. I will discuss how to teach complex molecules to fly in motional states compatible with state of the art de Broglie experiment and present advanced methods for their diffraction and detection.
Prof. Arndy is Full Professor of Quantum Nanonphysics at the University of Vienna and a founding member of the Vienna Center fro Quantum Science and Technology (VCQ). He is a world-leading expert in quantum effects in complex molecular systems and a pioneer in experimental matter-wave interferometry. He was Dean of the Faculty of Physics at the University of Vienna and Coordinator of the ESF network 'Molecule Interferometry and Metrology'. Prof. Arndt is the coordinator of the QU project NANOQUESTFIT, the awardee of an ERC Advance Grant and the recipient of the 2008 Wittgenstein-Preis which is the most prestigious Austrian science award.
