Asking if consciousness is computable is like asking if gravity is computable. A computer can simulate a star and calculate its gravitational influence, but that will never change the weight of the computer in the process. At best, computation might be able to predict better designs for the structures that make consciousness apparent. A more relevant question might be: Is it possible to engineer consciousness, or the possibility of consciousness into a computer?
Hypothetically I see no reason why not. It just requires the right materials and design. Now all we have to do is figure out what those materials and designs are. But before we start playing God with machines, maybe we should be asking whether or not we should engineer consciousness into machines in the first place.
Does our knowledge of what those materials and designs are warrant a "no reason why not"? Is consciousness substrate dependent as Searle's biological naturalism argues (and does that mean no/yes/or possibly to your hypothesis) or is substrate relevant only in terms of functional organization as Chalmers' argues:

"In any case, the conclusion is a strong one. It tells us that systems that duplicate our functional organization will be conscious even if they are made of silicon, constructed out of water-pipes, or instantiated in an entire population. The arguments in this paper can thus be seen as offering support to some of the ambitions of artificial intelligence. The arguments also make progress in constraining the principles in virtue of which consciousness depends on the physical. If successful, they show that biochemical and other non-organizational properties are at best indirectly relevant to the instantiation of experience, relevant only insofar as they play a role in determining functional organization."
Which means a lot of things could be conscious.
What does engineering "the possibility of consciousness" into a computer mean?
