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 computing advances raise concerns over 10,000 qubits breaking P‑256 encryption using Shor’s algorithm, driving urgency for quantum ECC attack awareness and post‑quantum migration strategies.

The only snag was that “Shor’s algorithm”, as it is now known, required something that at the time only existed on university blackboards: a quantum computer. Chart 1 These days, quantum ...

The quantum computing future is rapidly reshaping how scientists think about computation, with machines moving toward fault-tolerant systems capable of solving problems beyond classical limits. From ...

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

Some of the categories of algorithms: Factoring, Discrete Logarithms and the Abelian Hidden Subgroup Problem : like Shor’s algorithm. Quantum Walk Algorithms Quantum walks, sometimes called quantum ...

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 ...

This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...

The U.S. and China are racing to develop computers based on the properties of quantum physics – with implications for science and security.
