John Bartholomew talks about quantum memories and the challenges of keeping quantum information "coherent".
John explores the limit of how long quantum information can be stored - a "quantum memory" is an important part of quantum information technologies. He was part of a team that set the record for this "coherence time" of about 6 hours (using super-cold glowing crystals). This might seem short compared to classical hard drives, but its excitingly long enough to imagine building a quantum sneaker-net. In fact this idea of coherence gets at the boundary between quantum and classical! John shares his own journey from a small country town to a commute within view of the Eiffel Tower in Paris, and the super-fridges from Episode 1 make a reappearance.

What is Clear as Quantum?
Clear as Quantum is an EQUS podcast about quantum science and the exciting technologies that are getting ready to unleash a quantum revolution. In this “spooky podcast at a distance” we’ll try to dust the cobwebs out of the quantum physics realm that's entangling our lives. Over the course of 10 episodes you’ll hear from some of Australia’s leading quantum scientists, and learn things worth knowing about.
