Exploration of Constructor Theory
Constructor theory aims to generalize quantum theory by focusing on the notion of universal constructors, which perform any physically allowed task. This theory strives to define laws of physics in terms of what tasks are possible or impossible, thereby providing deeper insights into the limitations and capabilities of physical systems. Notably, the research emphasizes how some sets of states cannot be perfectly copied by the same machine, allowing a broader understanding of information systems beyond conventional quantum mechanics. The underlying aim is to connect various domains of physics and help formulate new theories that could enhance our grasp of fundamental problems.
