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?

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 ...

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

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.

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

Bitcoin quantum computing threat is real: experts say slow governance, not its cryptography, makes Bitcoin uniquely vulnerable to quantum attack — with 34% of supply already exposing public keys ...

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require nearly the resources anticipated just a year or two ago, two independently ...

One day soon, at a research lab near Santa Barbara or Seattle or a secret facility in the Chinese mountains, it will begin: the sudden unlocking of the world’s secrets. Your secrets. Cybersecurity ...

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 ...
