Silicon-based qubits have spin-orbits which are manipulated with magnetic fields more readily than other means available. Designers from the University of Wisconsin-Madison created the experimental device, based on silicon. Research scientists from Purdue University and the Technological University of Delft conducted the experimentation. The spin-orbit strength was found to be dependent on magnetic fields from external sources coupled with the silicon surface material; where qubits reside as quantum dots. Control of the qubits can thus be controlled in-part through control of the magnetic field. This capability lends quantum computing a boost which is needed for overall quantum information system control.
