Preparing for the Information Security Threat from Quantum Computers

A major threat posed by quantum computers is that they will be able to crack current standardized cryptography. A scalable quantum computer is still challenging to build from an engineering perspective, but there is an imminent threat to digital security and privacy where encrypted information, such as personally identifiable information, will remain valuable for a long time. The insights from our research provide guidelines on how IT departments and/or security solution providers can prepare to transform their currently quantum-vulnerable systems to quantum-resistant alternatives.(1,2)
