American and Australian researchers have published a paper in Nature outlining a design for a scalable , silicon quantum device using electrical interactions to couple and transform two - qubits logic circuits into expandable arrays . The " flip - flop qubits " are made up of alternating phosphorus qubits coupled using alternating electron interactions that have been extended over longer than normal distances ( > 150 nm ) by microwave resonators . The paper claims that the arrangement is much more fault- and fault - tolerant than previous designs and can be fabricated using existing silicon chip technology .
American and Australian researchers have published a paper in Nature outlining a design for a scalable, silicon quantum processor using electrical interactions to couple and integrate two-qubits logic gates into expandable arrays. The "flip-flop qubits" are made up of two phosphorus qubits coupled using donor electron interactions that have been extended over longer than normal distances (>150 nm) by microwave resonators. The team claims that the arrangement is much more fault- and noise-tolerant than previous designs and can be fabricated using existing silicon chip technology.
