Large-scale quantum computing will require the manipulation of quantum states of a physical system with well-behaved internal degrees of freedom. The internal quantum 'spin' states of single electrons confined to tiny potential wells (known as quantum dots) provide one such physical system.
Although the spin states of single electrons are long-lived, they are notoriously difficult to prepare and read out.
