Episode notes

The many worlds interpretation of quantum mechanics was first proposed in the 1950s. It paints a picture of multiple versions of reality being created by random events. So if you flip a coin, there are two new worlds created - one for heads and another for tails. The people who support the many worlds interpretation say that it's a logical conclusion of quantum mechanics. And it explains how quantum computers can do impossible calculations.

In the final episode of this Tech Tonic series, we hear how radical quantum ideas are reshaping our fundamental understanding of the universe. Nobel Prize winner Anton Zeilinger tells the FT’s Madhumita Murgia about the future of teleportation and the quantum internet; quantum computing pioneer David Deutsch makes the case for the theory that we live in a multiverse; and FT innovation editor John Thornhill speaks to physicist Carlo Rovelli about relational quantum mechanics.

Presented by Madhumita Murgia and John Thornhill, produced by Josh Gabert-Doyon and Edwin Lane. Executive producer is Manuela Saragosa. Sound design by Breen Turner and Samantha Giovinco. Original music by Metaphor Music. The FT’s head of audio is Cheryl Brumley.
