The Port of Los Angeles is one of the world’s busiest — and most inefficient. It’s now using an early quantum computing application to help solve its logistical bottlenecks.

Has it made a difference? The FT’s John Thornhill investigates. We hear from truck drivers at the Port of Los Angeles; Matt Schrap, CEO of the Harbor Trucking Association; SavantX co-founder Ed Heinbockel, who helped bring quantum computing to the port; and Alan Baratz, president of D-Wave Systems. Plus, John and FT artificial intelligence editor Madhumita Murgia discuss what optimisation at the Port of Los Angeles tells us about the future of quantum technology.

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. Special thanks to the National Quantum Computing Center for their help on this episode.
