Finally finished reading Quantum computing for cats

Yesterday I have finally finished John Gribbin's 'Quantum computing for cats'. A very good book if you want to know the history of computing and indeed about quantum physics itself, unfortunately the quantum computing was only found in the last chapter.  He mentioned the various experimental techniques now used to create these quantum computers such as ions, nuclear magnetic resonance and even using photons.  I think the technology is still too new to merit any more content, and I will give this 6/10.
