What do stock option pricing, drug discovery, and fraud detection have in common? They are among a growing number of applications that rely on rapid, precise calculations performed on massive volumes of data to uncover actionable insights. As powerful as supercomputers are, large-scale problems like these require even more processing power and capacity. This is where quantum computers come into play, with their ability to solve some of today’s intractable problems much more efficiently with enormous performance advantages, increased capacity, and better precision.

The impressive capabilities of quantum computing also present a new dilemma: once they become available some years from now, these mathematically astute computers will break current public-key cryptography and weaken the symmetric cryptographic algorithms. This presents a serious threat to the integrity and confidentiality of all our digital communications that rely on encryption, digital signatures, and communication protocols using digital certificates for proof of authenticity.
