(Phys.org)—When it comes to fabricating complex quantum devices,one limitation is the number of wires available on the measurement systems that the quantum devices are built on. Typically, controlling just three or four quantum dots requires about 20 wires, or which is the limit of many systems. In a fresh study,engineers beget devised a method that in principle can control 14 quantum dots using 19 wires. This improvement provides a way to build larger arrays of quantum devices, which could be useful for scaling up quantum computers and quantum information processing systems.
