Default 7 atom quantum dot transistor

Tiny dot speeds hi-tech future

Quote:
Scientists have created a transistor in a computer chip that is 10 times smaller than those commonly in use now, marking the start of a new age of super-fast, super-powerful computing.

At the heart of the electronic device is a "quantum dot" (pictured above), which measures just four-billionths of a metre — so small that it contains just seven atoms, compared to the millions that make up a typical laptop chip.
