I think they are related, in the following way:

Under the computational theory of mind, states of consciousness (including
particular visual experiences) are states of a computation.

Computation is nothing other than the processing of information. This
connects information (or rather, information processing) with consciousness.

Quantum mechanics is an emergent phenomenon which is explained by the fact
we are conscious computations.

See:

For an explanation of why QM follows from the computational theory of mind.
