Tracking the flow of quantum information

If objects in motion are like rainwater flowing through a gutter and landing in a puddle, then quantum objects in motion are like rainwater that might end up in a bunch of puddles, all at once. Figuring out where quantum objects actually go has frustrated scientists for years. Now researchers have derived a formula for understanding where quantum objects land when they are transmitted. It’s a development that offers insight for controlling open quantum systems in a variety of situations. From:: Engineering News — ScienceDaily
