Six-qubit quantum processor in silicium (IMAGE) Delft University of Technology Caption Image of the six qubit quantum processor described in this article. The qubits are created by tuning the voltage on the red, blue and green wires on the chip. The structures called SD1 and SD2 are extremely sensitive electric field sensors, which can even detect the charge of a single electron. These sensors together with advanced control schemes allowed the researchers to place individual electrons at the locations labeled (1)-(6), which were then operated as qubits.
