Physicists create a device that binds photons together to form “light molecules.”
A vacuum chamber the size of a shoebox has made history in Cambridge, Massachusetts. 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 …
