In this episode of The Quantum Kid, Katia Moskvitch and nine-year-old co-host Kai explore one of the most fascinating frontiers in modern physics: time travel, and what quantum mechanics and relativity really say about it. Our guest is Scott Aaronson — one of the world’s leading experts in quantum computing, the Schlumberger Centennial Chair of Computer Science at the University of Texas at Austin, and director of UT’s Quantum Information Center.
