Quantum computers Vs. Modern cryptography

Cryptography – securing data with mathematical principles – is crucial in today’s society, for instance to enable financial transactions, to secure medical records and to protect our national interests. In the future, computers could be built, based on principles from quantum physics. These computers threaten to undermine the foundations of modern cryptography. If we are to believe the popular media and a number of companies, this quantum age is rapidly approaching. Along with the ambiguity, anxiety also grows. This talk aims to clarify this complex matter. It discusses the basics of quantum computers, the complexity of building them, the threat they pose, and the preparations we need to make.
