Entangled Quantum Dots
From AScribe.org, Quantum Computers Are a Quantum Leap Closer: "The team used eight tiny converging wires, or 'gates,' to deposit the electrons in the dots one by one and then electronically fine-tune the dots' properties so they would become entangled. With these gates, the team was able to slowly tune the interacting dots so they are able to exist in a mixed, down-up and up-down configuration simultaneously."
