Episode notes

In Constructive Theory, a system is an information medium if it can be in at least two different states. The only concrete results that we can display at the moment is the fact that this is also enough to define quantum information. We think that construct a theory provides a very powerful tool for setting up a theory of measurement within a newly proposed theory of physics - even though it's conceptually strange.

This is my interview with David Deutsch, Visiting Professor of physics at the Centre for Quantum Computation, the Clarendon Laboratory, Oxford University and an Honorary Fellow of Wolfson College, Oxford. We discuss the constructor theory of information, some of its conjectured principles, the unification of classical and quantum information, and more.
