Abstract:

*We derive quantum theory from purely informational principles. Five elementary axioms—causality, perfect distinguishability, ideal compression, local distinguishability, and pure conditioning—define a broad class of theories of information processing that can be regarded as standard. One postulate—purification—singles out quantum theory within this class*.

Quantum mechanics continues to be one of the most puzzling and amazing theory of our time.

This is reminiscent of work by Peter Pesic. He starts with the postulate of the indistinguishability of elementary particles and derives the formalism of quantum mechanics. It's essentially an information-theoretical approach:
