Random numbers are increasingly important to our digitally connected world, with applications that include e-commerce, cryptography, and cloud computing. Producing a large amount of truly random numbers quickly, though, is a challenge.

To speed things up, a team of researchers has developed a compact laser that can produce these random numbers 100 times quicker than the fastest current systems. The results are published February 26 in the journal Science.

Yale researchers working with scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have demonstrated the ability to control spin dynamics in magnetic materials by altering the materials’ thickness. The research stands as a major achievement in the emerging field of spintronics — the manipulation of electron spin — and could prove useful in developing the next generation of electronics.
