The impending revolution of low-power quantum computers

By 2017, quantum physics will help reduce the energy consumption of our computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key issue. The next revolution ...

Fujitsu develops optical switch that cuts power consumption by half

Fujitsu Laboratories Limited today announced that it has been able to halve the power consumption of an optical waveguide switch based on silicon photonics through the world's first use of fine-patterned silicon germanium ...

Plasma as a fast optical switch

Laser uses relativistic effects to turn otherwise opaque plasma transparent, creating an ultra-fast optical switch useful in next-generation particle accelerators.
