American and Australian researchers have published a paper in silicon quantum processor outlining a design for a scalable, Nature 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.
