Relatively Certain

Hear the latest news about everything from quantum computers to astrophysics, all straight from scientists at the University of Maryland. Relatively Certain is produced by the Joint Quantum Institute and hosted by a rotating cast, featuring Chris Cesare, Emily Edwards and Dina Genkina. Episodes from Quantum Conversations, a prior series focused entirely on quantum physics, will remain available under the new name.

We all know that diamonds can hold great sentimental (and monetary) value. As luck may have it, diamonds—particularly defective ones, with little errors in their crystal structure—also hold great scientific value.

Fifty years ago, Theodore Maiman invented the laser. Steve Rolston and two guest experts describe how the device has utterly transformed quantum information science.

Modern timekeeping, and the ongoing effort to slice time into ever-thinner pieces, now depend critically on techniques of quantum information science.

TQW looks at recent research in the weird world of "ultracold" chemistry, where scientists have just discovered that chemical reactions can occur at only a few billionths of a degree above absolute zero.

A discussion of one of the most eerie aspects of quantum mechanics -- the utter randomness of measurements -- with guest Dr. Chris Monroe of JQI.

A primer on the fundamental terms and concepts of quantum information science, with guest Dr. Carl Williams, Chief of the Atomic Physics Division at the National Institute of Standards and Technology.
