Wolf, Stefan ; Winter, Andreas ; Huber, Marcus Erker, Paul 2019-02-20 More than a century ago, physicists around the world were collectively developing a theory to describe the newly discovered strange behaviours of some physical systems. This marks the birth of quantum theory. Few decades later, the groundbreaking idea to separate information from its physical carrier led to the establishment of information theory. These, initially independent theories, merged together in the last decades of the former century, leaving us with quantum information theory. This thesis will explore topics at the intersection of mathematics, physics and computer science, trying to elucidate the interwovenness of these three disciplines. While doing so, the results that were established during the years of studies leading up to this work are introduced. The question posed in the title will not be answered fully, as it may be too early still to give a definite answer to this multifaceted question. application/pdf https://localhost:5000/ark:/12658/srd1318991 https://susi.usi.ch/global/documents/318991 https://susi.usi.ch/documents/318991/files/2019INFO016.pdf eng info:eu-repo/semantics/altIdentifier/urn/urn:nbn:ch:rero-006-120176 info:eu-repo/semantics/altIdentifier/ark/12658/srd1318991 info:eu-repo/semantics/openAccess License undefined Quantum information theory Information Physics Quantum theory Computer science Mathematics Quantum clock Clocks Time Quantum mechanics info:eu-repo/classification/udc/004 Physics and information : what is the role of information in physics? http://purl.org/coar/resource_type/c_db06
