Quantum Computers are Reality Simulators - Dr. Steve Girvin, Yale University - DSPod #303

Yale's Steve Girvin is a pioneer of quantum computing, and our
guide for our first foray into understanding how these systems do
and don't work. Over the course of our conversation, we come to
realize that quantum computers are not performing computations
per se - they're more devices that an be used to answer a
specific set of questions about reality. We dig into the details
of why some questions can only be answered with a quantum
computer, how next generation encryption services will come with
a way of detecting eavesdroppers, and try once more to understand
if there's a way of looking at the Stern Gerlach experiment that
doesn't need any kind of magic. PATREON: get episodes early +

https://bit.ly/3v3kz2S PODCAST INFO: Anastasia completed her PhD
studying bioelectricity at Columbia University. When not talking
to brilliant people or making movies, she spends her time
painting, reading, and guiding backcountry excursions. Shilo also
did his PhD at Columbia studying the elastic properties of
molecular water. When he's not in the film studio, he's exploring
sound in music. They are both freelance professors at various
universities. - Blog: http://DemystifySci.com/blog - RSS:
