Typical laser devices are designed to minimize these fluctuations to produce light of steady intensity: they make the light waves bounce around inside the material to force its atoms to emit more and more photons in sync with each other.Д«ut for random-number generation, researchers aim for the opposite.

To make encryption safer, researchers have turned to quantum mechanics, where the laws of physics guarantee that the results of certain measurements-such as when a radioactive atom decays-are genuinely random.ДЄ popular way to tap into quantum randomness is to exploit fluctuations in how photons are emitted by the materials used in lasers.

This makes them at least partially predictable, and therefore vulnerable to being decoded. Algorithms in conventional computers can produce sequences of numbers that seem random at first, but over time these tend to display patterns. True randomness is surprisingly difficult to come by. It exploits fluctuations in the intensity of light to generate randomness-a coveted resource in applications such as data encryption and scientific simulations-and could lead to devices that are small enough to fit on a single computer chip.
