These chips are typically made from thin slices of silicon with complex components laid out on them in specific patterns. These patterns control the flow of current using electrical switches ...

Flipping an on-off electrical switch in the material takes a mere 1 trillionth of a second, thousands of times faster than silicon-based transistors, U.S. researchers say.
