Electrically switchable qubit (IMAGE) University of Basel Caption A nanowire made of germanium and silicon (blue/green) lies on electrodes known as gates (gold). Voltages applied to the gates lead to the formation of individual spin qubits (blue and red arrows) that can be manipulated by microwave signals (blue pulse). In one mode, the qubit is slow and the quantum information is more stable (blue spin). In the other, the qubit can be changed more quickly (red spin).
