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?

Quantum factor: the Paul trap used by Monz and colleagues. (Courtesy: C Lackner/Quantum Optics and Spectroscopy Group, University of Innsbruck) A quantum computer made of five trapped ions has been ...

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

Researchers report that they have designed and built a quantum computer from five atoms in an ion trap. The computer uses laser pulses to carry out Shor's algorithm on each atom, to correctly factor ...

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 ...

Arxiv – Pretending to factor large numbers on a quantum computer – Shor’s algorithm for factoring in polynomial time on a quantum computer gives an enormous advantage over all known classical ...
