 Until recently the general opinion was that the various notions of information were more or less isolated but in recent years considerable progress has been made in the understanding of the relationship between these concepts. Cover and Thomas (2006), for instance, see a perfect match between Kolmogorov complexity and Shannon information. Similar observations have been made by Grünwald and Vitányi (2008). Also the connections that exist between the theory of thermodynamics and information theory have been studied (Bais &amp; Farmer 2008; Harremoës &amp; Topsøe 2008) and it is clear that the connections between physics and information theory are much more elaborate than a mere ad hoc similarity between the formal treatment of entropy and information suggests (Gell-Mann &amp; Lloyd 2003; Verlinde (2011, 2017). Quantum computing is at this moment not developed to a point where it is effectively more powerful than classical computing, but this threshold might be passed in the coming years. From the point of view of philosophy many conceptual problems of quantum physics and information theory seem to merge into one field of related questions:
