The countdown is on to Q-Day, when an algorithm written more than 30 years ago could run on a quantum computer and compromise the security of data on the internet. How are we preparing?

A quantum computer algorithm that is used to find the prime factors in an encryption key. Created by applied mathematician Peter Shor in the mid-1990s, Shor's algorithm may be used to break the codes ...

Modern internet security relies heavily on mathematical problems that ordinary computers cannot solve within a useful time. A ...

As quantum computing moves closer to becoming reality, bad actors are already harvesting data to crack encryption later.

The rise of quantum computing and its implications for current encryption standards are well known. But why exactly should quantum computers be especially adept at breaking encryption? The answer is a ...

In 1994, a Bell Labs mathematician named Peter Shor cooked up an algorithm with frightening potential. By vastly reducing the computing resources required to factor large numbers—to break them down ...

Whether we realize it or not, cryptography is the fundamental building block on which our digital lives are based. Without sufficient cryptography and the inherent trust that it engenders, every ...

Building on a landmark algorithm, researchers propose a way to make a smaller and more noise-tolerant quantum factoring circuit for cryptography. The most recent email you sent was likely encrypted ...

Three weeks ago, panic swept across some corners of the security world after researchers discovered a breakthrough that, at long last, put the cracking of the widely used RSA encryption scheme within ...

MIT’s Peter Shor explains why he devised an algorithm for a quantum computer that could unravel our online data encryption Internet security relies on the fact that our computers can’t break its ...

It’s proven that today’s encryption is vulnerable to attack by a sufficiently mature quantum computer running Shor’s algorithm - a catastrophic event commonly known as Q-Day. Even before such a ...
