Turning Light into Matter
Physicists have created a device that binds photons together to form "light molecules."
In a lab in Cambridge, Mass., a vacuum chamber the size of a shoebox has made history. Here, Harvard physicist Ofer Firstenberg has created a new form of matter: a pair of photons, stuck together. The “light molecule” is, potentially, the building block of technology that uses some form of tangible light — from light sculptures to lightsabers to (perhaps more practically) computers that can perform vastly more complex calculations than today’s machines.
Unlike atoms and ...
