Researchers build all-optical transistor; device could lead to new quantum computer design

The results of the study could be used to create computing chips with a longer-lasting battery and faster processing speeds.

Optical computing, or the use of light instead of electricity to complete calculations, is the most significant difference between traditional and quantum computers. Using optical computing, computers can make calculations much faster than traditional computers. Optical computing, as suggested by the name, requires light particles, or photons, to function. When two photons encounter one another, however, they tend to just pass through each other, making this technology difficult to achieve, Headlines & Global News explains.

A research team consisting of scientists from Massachusetts Institute of Technology (MIT) Research Laboratory of Electronics, Vienna University of Technology, and Harvard University came together to investigate how to manipulate the behavior of photons in order to create a successful optical computer server.
