Lorraine Ford well I must explain you why his works and this quantum guitar and bloch sphere are revolutionary because apparently you don t understand and critic without real relevances. He does not change the QM, He changes how we think, reason and compute. So he goes beyond the actual computing with linear algebras, complex vector spaces, matrix , so he improves the visualizations, the compositions, the intuitions. It is about how we approach the symbols and how we see them and it is important. The Bloch sphere so is relevant in this case with the poles and links with qubits, so there is a relevant point because we turn the abstraction to geometry and I utilise this in my theory and these 3d spheres.Superpositions, phases, rotations,quantum gates........it is exactly what needs the QM to have this intuition inserted, and so the consciousness probably and knowledges. In his book quantum in pictures, he replaces furthermore the equations with diagrams and utilises wires , boxes, connections, so the systems have processings and interactions. So he improves the category theory in making it visual and compositional simply. So now in considering the quantum guitar , so he links with strings theory, and me I prefer to links to 3D spherical volumes , so we have quantum systems, strings or spheres, after operations and entanglements and if we consider the harmony , that becomes relevant if the volumes, oscillations, rotations, motions are considered and the combinations are infinite. The volumes I think are very very important and we can apply the tensors, the transformations....the musical strings or spheres becomes very relevant universally speaking to be more concrete than the abstraction we had the habit to use. So yes his works are revolutionary because the composition are natural, the systems become visual. Before the entanglements were abstract, but with his giagrams and quantum guitare it is not anymore. There are structures in the computations now, so it is more than just numbers in resume , here we have transformations of structures. So he unifies many things , from algebra to processes, from numbers to relations,.... The categories can be also utilised for the quantum computing in creating different domains even in having thre same structures. It gives better reasonings and a possible way universal with the spherical volumes. The relevamce also is that we can justmake error corrections easier with the manipulations of his diagrams instead of difficult algebra problems, so it is about interactions and not just algorythms and it is important. We have here relations, physical and not just abstractions,, it is not just symbolic. We have a better universal way for the quantum mechanism, the reality, the processes, the relations and interactions. We go beyond static objects with numbers. That permits to have possible quantum computation about transforming connected processes instead of manipulated equations. So Bob Coecke works permit to turn QM from calculations into a thing we see and can compose.
