In the world of engineering, “noise” – random fluctuations from environmental sources such as heat – is generally a bad thing. In electronic circuits, it is unavoidable, and as circuits get smaller and smaller, noise has a greater and more detrimental effect on a circuit’s performance. Now some scientists are saying: if you can’t beat it, use it.
