The advent of widely available quantum computing poses an existential threat to present techniques and standards of cryptography. William Gee, partner, innovation and digitalisation, PWC, and Andrew Cheung, president and chief executive officer of 01 Communique Lab, join Lewis McLellan, editor of OMFIF’s Digital Monetary Institute, to discuss the implications of a new, more powerful type of computing that will render present cryptographic standards obsolete. They explore the consequences of the proliferation of quantum computing, the risks it poses and the steps being taken to mitigate them.
