This episode of the Physics World Weekly podcast features an interview with Chris Schnabel, who talks about the threats and opportunities that quantum technologies pose to organizations that rely on cryptographic systems.

Schnabel is vice president of product at Qrypt, a US-based company that uses quantum technology to generate random numbers for cryptography and other applications. He explains how modern cryptography systems could be compromised by quantum computers of the future – and how quantum technologies can be used to achieve secure communications.
