JQI Podcast Episode 4

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

Recent Podcast Episodes

This past March, NIST Fellows Joseph Reader and Charles Clark co-authored an article in Physics Today: "1932, a watershed year in nuclear physics."

In a small detour from our typical quantum conversation, Charles sat down with Phil to recount some remarkable nuclear physics discoveries made that year. This podcast details the search for an isotope of hydrogen, culminating in the discovery of deuterium (heavy water).

Phil Schewe discusses quantized energy levels with Steve Rolston (JQI) and Wes Campbell (former JQI postdoc and current UCLA professor). The concept of electronic energy levels in an atom has applications everywhere, from sodium lamps to brake lights to quantum information and atomic clocks.

Can you see a single photon? Does it weigh anything? Emily Edwards talks to Alan Migdall, an expert on single photon technology. Part 2 of three installments on photons.
