Quantum computing could lead to revolutions in cryptography, materials design and telecommunications. But fulfilling those ...

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 ...

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

Researchers affiliated with Caltech and the quantum computing startup Oratomic have published a preprint claiming that Shor’s algorithm, the theoretical tool capable of breaking widely used public-key ...

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 ...

A new quantum-inspired algorithm has cracked a problem so massive that conventional supercomputers struggle to even approach ...

The very prospect of the quantum apocalypse has driven various stakeholders to consider what that could be like and how to prepare. For instance, in 2015, the U.S. Natio ...

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 ...

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 ...

Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...

The day when a quantum computer can crack commonly used forms of encryption is drawing closer. The world isn’t prepared, ...
