Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require ...

A new quantum-inspired algorithm has cracked a problem so massive that conventional supercomputers struggle to even approach it. Researchers used the method to simulate extraordinarily complex quantum ...

While post-quantum security standards and technical solutions are rapidly advancing, Quantus’ Chris Smith argues that Bitcoin ...

Recent research papers posted to arXiv have sharply reduced the estimated computing power a quantum machine would need to crack the encryption protecting major cryptocurrencies and other digital ...

Somewhere on a blockchain right now, a Bitcoin address that last moved coins in 2015 is sitting with its public key fully exposed, waiting for its owner to return. That owner may have years to act, or ...

By the time Bitcoin and other networks are ready to defend themselves, it may already be too late, according to a new ...

A new report by Capgemini warns that quantum computing may break the widely used public-key cryptographic systems within the next decade — threatening everything from online banking to blockchain ...

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 ...

Charles H. Bennett and Gilles Brassard on the collaboration that led them to the 2025 ACM A.M. Turing Award.

Quantum computing does not just threaten passwords and virtual private networks (VPNs). It goes straight for something legal systems rely on ...
