Ion experiment aces quantum scrambling test

Researchers at the Joint Quantum Institute have implemented an experimental test for quantum scrambling, a chaotic shuffling of the information stored among a collection of quantum particles. Their experiments on a group of seven atomic ions, reported in the March 7 issue of Nature, demonstrate a new way to distinguish between scrambling—which maintains the amount of information in a quantum system but mixes it up—and true information loss.

Black holes: The ultimate cosmic whisks

Chaos. Time travel. Quantum entanglement. Each may play a role in figuring out whether black holes are the universe’s ultimate information scramblers.

In this episode of Relatively Certain, Chris sits down with Brian Swingle, a QuICS Fellow and assistant professor of physics at UMD, to learn about some of the latest theoretical research on black holes—and how experiments to test some of these theories are getting tantalizingly close.
