It can generate 250 terabytes of random bits per second. In fact, it was so fast that the team behind it struggled to record its output using a high-speed camera. According to the researchers, their system trumps physical random number generators both in speed and through its ability to create many bitstreams simultaneously. The results are published in the journal Science. The new invention utilizes a tiny laser, just one millimeter long, which bounces light between mirrors positioned at either end of an hourglass-shaped cavity before exiting the device, reports Science News. Unlike previous laser-based systems, the new process can...
