MIT researchers build an all-optical transistor

Optical computing—using light rather than electricity to perform calculations—could pay dividends for both conventional computers and quantum computers, largely hypothetical devices that could perform some types of computations ...

Two stopped light pulses interact with each other

( -- For the first time, physicists have experimentally demonstrated the interaction of two motionless light pulses. Because the stopped light pulses have a long interaction time, it increases the efficiency with ...

More reliable way to produce single photons

Physicists at the University of Bath have developed a technique to more reliably produce single photons that can be imprinted with quantum information.
