What is exactly Weizsäcker's ur-alternatives theory? How is it related to digital physics theories? Is it related to pancomputationalism? Does it defend that a universe can be described as being fundamentally made of qubits? Would this mean that that universe would be fundamentally made by information? Would this mean that, in this theory, a universe could be itself like a quantum computer?

Yes, this was his basic philosophical idea. But it is not a viable theory.

You can indirectly infer this from the fact that it appeared only in three philosophically oriented books [25-27] in the Wikipedia article, and nobody else worked on it.

He builds up infinite-dimensional Hilbert spaces from 2-dimensional ones (qubits), but fails to derive or explain the Lie algebra representations needed to equip the latter with the right physical structure.

And if universe would be made of information, would that mean that the universe would be some kind of computer quantum itself like pancomputationalism says?
