Semiconductor qubits scale in two dimensions

CPUs are built using semiconductor technology, which
is capable of putting billions of transistors onto a single chip.
Now, researchers from the group of Menno Veldhorst at QuTech, a
collaboration between TU Delft and TNO, have shown that this
technology can be used to build a two-dimensional array of qubits
to function as a quantum processor. Their work, a crucial milestone
for scalable quantum technology, was published today in
Nature.
