itatively different to a traditional computer in order to break the Turing limit. The obvious place to turn is the quantum world. Quantum Computers Quantum computers have had an extraordinary run in the press recently. It has been variously claimed they offer limitless computing power and can break all k

’s Chinese Room, this is the same process the man in the room followed: get a symbol, look it up in a book, and reply with the corresponding symbol. Universal Turing Machine We have missed one important step from our explanation of the modern computer: the ability to run programs. Nowadays, we take for granted you can do
