As Douglas_Knight’s link points out, the lossless integration model has been falsified experimentally, so the “formulation of consciousness as a lossless integration of information” does not apply to the actual observed consciousness. The math may or may not be interesting in itself, but it has no bearing on whether “sentient robots” are possible. Fortunately, the authors’ conclusion is suitably qualified (emphasis mine):
This result implies that if unitary consciousness exists, it cannot be modelled computationally.

In other words, well, unitary consciousness doesn’t exist. Score one more for the Buddhists.
