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. In the paper, which was presented at the International Conference on Quantum Information (ICQI), the authors describe how they developed an algorithm capable of implementing this design. and noise-tolerant than previous designs and can be fabricated using existing silicon chip technology.

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.
