Toshiba Europe's QKD hardware
Toshiba Europe has been at the forefront of QKD hardware development for several years. Now, the technology has been shown to work over conventional optical fiber, with the potential to operate over links up to 120 km long. Other partners in the UK demonstration are working to shrink QKD hardware dramatically, potentially making it compatible with hand-held devices. Photo: Toshiba Europe.
