Somersaulting spin qubits for universal quantum logic could enhance control in larger arrays

"quantum dot qubit logic based on hopping of spins/ gates... microwave signals, traditionally used to control qubits,  no longer needed... instead, baseband signals/ small magnetic fields more simply achieve universal qubit control. .. germanium semiconductors enable dot-to dot jumping from 1 platform to next creating torque enabling somersaults and spin rotation control... error rates less than 1K for 1-qubit gates, less than 100 for 2-qubit gates... controlled routines enabling hop spins to any quantum dot in 10-quantum dot array"
