Toshiba developing quantum repeater
Toshiba is developing a device it hopes will allow for global quantum key distribution.
The company is developing a quantum repeater, a device to regenerate a quantum key once quantum entanglement has been split into channels for transmission.
"The device is under development," said Andrew Shields, group leader of Toshiba's quantum information technology group. "We have a European collaboration."
Shields said that another technology important for extending the range of quantum key distribution was the use of satellites, but his team was focused on fibre-optics.

Good plan with with the fiber optics. Once they are in place, it would be worth thinking about the satellites. The problem is, that satellites can now be held to ransom up there in space, with the added bonus of plausible deniability, not to mention tumbling rocks, solar electromagnetic shocks and lost screwdrivers.
