Silicon qubits plus light add up to new quantum computing capability
(PHYSorg.com Physics)

A silicon-based quantum computing device could be closer than ever due to a new experimental device that demonstrates the potential to use light as a messenger to connect quantum bits of information-known as qubits-that are not immediately adjacent to each other. The feat is a step toward making quantum computing devices from silicon, the same material used in today`s smartphones and computers.
