SCALABLE COMPUTER ARCHITECTURAL FRAMEWORK FOR QUANTUM OR CLASSICAL DIGITAL COMPUTERS

Scalable computer architectural frameworks for quantum computers or for classical digital computers. According to one implementation, the framework includes a plurality of processing nodes, each processing node including at least three processing elements, and a plurality of couplings. The processing elements in a processing node ( 11 ) are connected in series forming a string comprising two end processing elements and at least one intermediate processing element. Each processing node is connected to each of the other processing nodes by means of only one external coupling. The intermediate processing elements are connected to processing elements of other processing nodes by the same number of external couplings, and the end processing elements are connected to processing elements of other processing nodes by the same number of external couplings or one more.
