A method of operating a quantum system comprising computational elements, including an insulated ring of superconductive material, and semi-closed rings used as an interface between the computational elements and the external world, is disclosed. In one aspect, the method comprises providing an electrical signal, e.g. a current, in an input ring magnetically coupled to a computational element, which generates a magnetic field in the computational element and sensing the change in the current and/or voltage of an output element magnetically coupled to the computational element. The electrical input signal can be an AC signal or a DC signal. The computational element is electromagnetically coupled with other adjacent computational elements and/or with the interface elements. The corresponding magnetic flux between the computational elements and/or the interface elements acts as an information carrier. Ferromagnetic cores are used to improve the magnetic coupling between adjacent elements.

Method of operating quantum-mechanical memory and computational devices

A method of forming a quantum system comprising computational elements, consisting of an insulated ring of superconductive material, and semi-closed rings, which are used as an interface or input/output facility between the quantum bit and the external world, is disclosed. Faraday induction is used to provide electromagnetic coupling between adjacent computational elements and between the computational elements with interface elements of the quantum system. Therefore the corresponding magnetic flux acts as an information carrier. Ferromagnetic cores are used to improve the magnetic coupling between adjacent elements of the quantum system.
