What Is the True Promise of Quantum Computing? | Podcast: The Joy of Why
Despite the hype, it’s been surprisingly challenging to find quantum algorithms that outperform classical ones. In this episode, UC Berkeley computer scientist, Ewin Tang, discusses her pioneering work in “dequantizing” quantum algorithms and what it means for the future of quantum computing.“The Joy of Why” is a Quanta Magazine podcast about curiosity and the pursuit of knowledge. The mathematician and author Steven Strogatz and the astrophysicist and author Janna Levin take turns interviewing leading researchers about the great scientific and mathematical questions of our time.
