Provided are organic silicon oxide fine particles which can be formed into a porous film having a dielectric constant and mechanical strength expected as a high-performance porous insulating film and having excellent chemical stability, and a preparation method thereof. Described specifically, provided are an organic silicon oxide fine particle comprising a core containing at least an inorganic silicon oxide or an organic silicon oxide and a shell containing at least an organic silicon oxide and being formed around the core by using shell-forming hydrolyzable silane in the presence of a basic catalyst; wherein of silicon atoms constituting the core or the shell, a ratio (T / Q) of a number (T) of silicon atoms having at least one bond directly attached to a carbon atom to a number (Q) of silicon atoms having all of four bonds attached to an oxygen atom is greater in the shell than in the core; and wherein the shell-forming hydrolyzable silane comprise at least a hydrolyzable silane compound having two or more hydrolyzable-group-having silicon atoms bound to each other via a carbon chain or via a carbon chain containing one silicon atom between some carbon atoms.

This invention concerns a method to switch on and off the exchange interaction J between electron spins bound to donor atoms. The electron spins have the role of ‘qubits’ to carry quantum information, and the exchange interaction J has the role of mediator for two-qubit quantum logic operations. The invention aims at exploiting the existence of a further magnetic interaction, the hyperfine interaction A, between each electron spin and the nuclear spin of the donor atom (301, 302) that binds the electron. The hyperfine interaction A, together with the ability to read out (504) and control the state of the nuclear spins, is used to suppress the effect of the exchange interaction J at all times, except while a quantum logic operation is being performed. In this way, the result of the quantum logic operation is not distorted after the operation has taken place. In a further aspect, the invention concerns an electronic device where the method can be practically implemented, and a large scale device made up of many of the devices.
