Vertical cavity quantum switch could lead us away from electronics-based computing

Right now, many researchers around the world are working on ways to move away from electronics-dominated computing systems. There are a number of ideas about how this can be accomplished. "We are trying to demonstrate an all-optical switch that, at the first stage, could be used in ultrafast optical communication systems," Chaoyuan Jin tells PhysOrg.com. "It might also be useful for optical interconnection to replace present day electronic links which transfer tremendous data between computer chips, or perhaps useful for optical computing on-chip."
